The One

Two novel symmetric fluorene-based ligands, namely, 2,7-bis(1H-imidazol-1-yl)-9,9-dimethyl-9H-fluorene [L1 or (I), C21H18N4] and 2,7-bis(1H-imidazol-1-yl)-9,9-dipropyl-9H-fluorene (L2), have been used to construct the coordination polymerscatena-poly[[dichloridodicopper(I)(Cu—Cu)]-μ-2,7-bis(1H-imidazol-1-yl)-9,9-dimethyl-9H-fluorene], [Cu2Cl2(C21H18N4)]n, (II), andcatena-poly[[tetra-μ2-chlorido-tetracopper(I)]-bis[μ-2,7-bis(1H-imidazol-1-yl)-9,9-dipropyl-9H-fluorene]], [Cu4Cl4(C25H26N4)2]n, (III). There are three types of C—H...N hydrogen bonds in (I), resulting a two-dimensional network in theabplane, including a chiral helical chain along thebaxis. Compounds (II) and (III) are related one-dimensional polymers. In both, CuIatoms connect the symmetric ligands (L1 orL2) into a one-dimensional chain. In (II), the {[CuICl2]−} unit, acting as a co-anion, adheres to the one-dimensional chain through a weak Cu...Cu interaction. However, in (III), the {[CuI2Cl4]2−} unit links two different chains into a one-dimensional rope-ladder-type chain. In addition, there are C—H...Cl hydrogen bonds and π–π interactions in the extended structures of (II) and (III), the difference is that the chains in (II) are linked into a two-dimensional network while the chains in (III) are stacked into a three-dimensional framework.

The title compound, [MnCl2(C24H20N6)], has been synthesized and characterized based on the multifunctional ligand 2,5-bis(2,2′-bipyridyl-6-yl)-3,4-diazahexa-2,4-diene (L). The MnIIcentre is five-coordinate with an approximately square-pyramidal geometry. TheLligand acts as a tridendate chelating ligand. The mononuclear molecules are bridged into a one-dimensional chain by two C—H...Cl hydrogen bonds. These chains are assembled into a two-dimensional layer through π–π stacking interactions between adjacent uncoordinated bipyridyl groups. Furthermore, a three-dimensional supramolecular framework is attained through π–π stacking interactions between adjacent coordinated bipyridyl groups.

The rigid organic ligand (pyridine-3,5-diyl)diphosphonic acid has been used to create the title novel three-dimensional coordination polymer, [Ca(C5H6NO6P2)2(H2O)]n. The six-coordinate calcium ion is in a distorted octahedral environment, formed by five phosphonate O atoms from five different (pyridin-1-ium-3,5-diyl)diphosphonate ligands, two of which are unique, and one water O atom. Two crystallographically independent acid monoanions,L1 andL2, serve to link metal centres using two different coordination modes,viz.η2μ2and η3μ3, respectively. The latter ligand,L2, forms a strongly undulated two-dimensional framework parallel to the crystallographicbcplane, whereas the former ligand,L1, is utilized in the formation of one-dimensional helical chains in the [010] direction. The two sublattices ofL1 andL2 interweave at the Ca2+ions to form a three-dimensional framework. In addition, multiple O—H...O and N—H...O hydrogen bonds stabilize the three-dimensional coordination network. Topologically, the three-dimensional framework can be simplified as a very unusual (2,3,5)-connected three-nodal net represented by the Schläfli symbol (4·82)(4·88·10)(8).

In the title compound, [CdNi(C9H8N2)2(CN)4] n , the Cd and Ni atoms both lie on centres of inversion in space group P21/c. The Cd atom is coordinated by two bidentate quinolin-8-amine ligands and by the N atoms of two cyano ligands, while the square planar Ni atom is coordinated by the C atoms of four cyano ligands. These units form a one-dimensional coordination polymer containing an (–NC—Ni—CN—Cd–) n backbone, and the coordination polymer chains are linked into a three-dimensional array by a combination of N—H...N and C—H...N hydrogen bonds, augmented by a π–π stacking interaction.

In 4,4′-biphenol–1,4-diazabicyclo[2.2.2]octane (1/1), C12H10O2.C6H12N2 (1), monoclinic, C2/c, a = 12.1510 (9), b = 6.3202 (4), c = 21.051 (2) Å, β = 98.875 (10)° with Z = 4, the biphenol units lie across twofold rotation axes and the diamine units are disordered across centres of inversion. The molecular components are linked by means of O—H...N hydrogen bonds into zigzag chains with graph set C^{2}_{2}(16) running parallel to the [201] direction; the chains are not coiled and there are no interactions between neighbouring chains. In 4,4′-biphenol–1,2-diaminoethane–methanol (2/1/1), (C12H10O2)2.C2H8N2.CH4O (2), triclinic, P1¯, a = 9.4592 (7), b = 10.6311 (10), c = 12.2085 (14) Å, α = 91.812 (9), β = 93.091 (6), γ = 90.652 (6)° with Z = 2, there are seven independent hydrogen bonds of O—H...O, O—H...N and N—H...O types and each oxygen and each nitrogen acts as a single donor and single acceptor of hydrogen bonds. The four independent components are linked by means of O—H...O and O—H...N hydrogen bonds into a linear aggregate, and further O—H...N and O—H...O hydrogen bonds generate chains in the [011] direction containing alternating biphenol and diamine units, and in the [021] direction containing methanol and pairs of biphenol molecules. These two types of chain intersect to form a continuous two-dimensional net, graph set R^{10}_{10}(62), with biphenol molecules at the nodes: pairs of these nets are linked into bilayers by N—H...O hydrogen bonds, but the nets are not interwoven. In 4,4′-biphenol–1,2-diaminoethane (1/1), C12H10O2.C2H8N2 (3), monoclinic, P21/a, a = 8.2121 (5), b = 5.3401 (3), c = 14.6014 (9) Å, β = 99.962 (7)° with Z = 2, each of the components lies across a centre of inversion. The O atoms act as single donors and double acceptors of hydrogen bonds and the N atoms as double donors and single acceptors, so that both oxygen and nitrogen are effectively four-coordinate; all the hydrogen bonds are of O—H...N or N—H...O type. Chains built from N—H...O and O—H...N hydrogen bonds run parallel to [100] and [010] and the intersection of these gives two-dimensional nets built from R^{6}_{6}(12) rings: these nets are linked by the —C6H4C6H4— and —CH2CH2— spacer units into a continuous three-dimensional diamondoid structure.

In the title compound, {[Ag(C6H8N2)(H2O)](C6H4Cl2NO3S)} n , the AgI ion is three-coordinated by two N atoms from two symmetry-related 2,3-dimethylpyrazine (dmp) ligands, and one water O atom in a distorted trigonal–planar geometry. The dmp ligands bridge AgI ions to form a one-dimensional chain structure with charge-balancing 4-amino-2,5-dichlorobenzenesulfonate anions. In the crystal structure, intermolecular O—H...O and N—H...O hydrogen bonds form a two-dimensional network.

The title compound, {(C6H14N2O2)[Cu2Cl6(H2O)]}n, consists of 1,4-dihydroxy-1,4-diazoniabicyclo[2.2.2]octane dications and one-dimensional inorganic anionic {[Cu2Cl6(H2O)]2−}nchains in which both five-coordinate [CuCl3(H2O)]−and five-coordinate [CuCl3]−units exist. These two distinct type of unit are linked together by one chloride ion and are bridged across centres of inversion to further units of their own type through two chloride ions, giving rise to novel polymeric zigzag chains parallel to thecaxis. The chains are connected by O—H...Cl hydrogen bonds to produceR24(16) ring motifs, resulting in two-dimensional layers parallel to theacplane. These layers are linked into a three-dimensional framework with the organic cationsviaO—H...Cl hydrogen bonds. Hydrogen bonding between the chains, and between the chains and the organic cations, provides stability to the crystal structure.

The structures of six symmetrically 4,6-disubstituted 2-aminopyrimidines, four of them containing a 5-nitroso substituent, have been determined. The nitroso compounds, in particular, exhibit polarized molecular–electronic structures leading to extensive charge-assisted hydrogen bonding. The intermolecular interactions observed include hard hydrogen bonds of N—H...N and N—H...O types together with O—H...O and O—H...N types in 2-amino-4,6-bis(2-hydroxyethylamino)-5-nitrosopyrimidine; soft hydrogen bonds of the C—H...O type in both 2-amino-4,6-bis(morpholino)-5-nitrosopyrimidine (3) and 2-amino-4,6-bis(benzylamino)-5-nitrosopyrimidine (4), and of the C—H...π(arene) type in both 2-amino-4,6-bis(piperidino)pyrimidine (1) and 2-amino-5-nitroso-4,6-bis(3-pyridylmethoxy)pyrimidine (5); and aromatic π...π stacking interactions in 2-amino-5-nitroso-4,6-bis(3-pyridylmethoxy)pyrimidine. The supramolecular structures formed by the hard hydrogen bonds are finite, zero-dimensional in (1), one-dimensional in 2-amino-4,6-bis(3-pyridylmethoxy)pyrimidine (2), two-dimensional in both (3) and (4), and three-dimensional in both (5) and 2-amino-4,6-bis(2-hydroxyethylamino)-5-nitrosopyrimidine.
