Abstract H2bpe(H2PO3)2 (1) and H2bpe(H2PO4)2 ・H2O (2) (H2bpe = ethene-trans-1,2-bis(4-pyridinium), H2PO3 = dihydrogenphosphite, and H2PO4 = dihydrogenphosphate) have been prepared and structurally characterized. In compound 1, the dihydrogenphosphite anions form dimers, with a P···P distance of 4.2073(7) Å , by two O-H···H hydrogen bonds, and the dimeric dihydrogenphosphite units interact with the H2bpe cations by way of N-H···O and O-H···O hydrogen bonds, resulting in a one-dimensional chain. The chains are held together by C-H···O interactions. In compound 2, the phosphate ions are connected by O-H···O hydrogen bonds into an unusual 2D square gridtype framework with P···P separations ranging from 4.7533(7) to 4.9506(8) Å . The H2bpe cations crosslink the dihydrogen phosphate layers by N-H···O hydrogen bonds, forming a three-dimensional supramolecular network with channels. The water molecules in compound 2 occupy these channels and make O-H···O bonds to adjacent phosphate O atoms and also O-H···O bonds to the next water O atom in the channel.

The title compound, C2H10N2 2+·2Cl−·2C12H8N2·4H2O, has an inversion centre located midway between the two C atoms of the ethylenediammonium cation. The 1,10-phenanthroline molecules stack along the a axis, and are linked by π–π stacking interactions to form one-dimensional chains. These are bridged by ethylenediammonium cations, via hydrogen bonds, forming two-dimensional supramolecular sheets parallel to the ac plane. Hydrogen bonds to chloride anions and water molecules connect these two-dimensional sheets, resulting in the formation of a three-dimensional supramolecular network.

In the title polymeric complex, {[Fe(C12H10N2)2(H2O)4](CH3C6H4SO3)2·2CH3OH}n, the FeIIcation, located on an inversion centre, is coordinated by four water molecules in the equatorial positions and two 1,2-bis(pyridin-4-yl)ethene molecules in the axial positions. This results in a distorted octahedral geometry for the [N2O4] coordination polyhedron. The 1,2-bis(pyridin-4-yl)ethene molecules bridge the FeIIcations, forming polymeric chains running along thea-axis direction. Stabilization of the crystal structure is provided by O—H...O hydrogen bonds; these are formed by coordinated water molecules as donors towards the O atoms of the methanol molecules and tosylate anions as acceptors of protons, leading to the formation of a three-dimensional supramolecular network. Weak C—H...O hydrogen bonds are also observed in the crystal.

The title compound, {[Co(H2O)6][Co(SO4)(C10H8N2)(H2O)3][Co(SO4)2(C10H8N2)(H2O)2]}n, contains three crystallographically unique CoIIcentres, all of which are in six-coordinated environments. One CoIIcentre is coordinated by two bridging 4,4′-bipyridine (4,4′-bipy) ligands, one sulfate ion and three aqua ligands. The second CoIIcentre is surrounded by two N atoms of two 4,4′-bipy ligands and four O atoms,i.e.two O atoms from two monodentate sulfate ions and two from water molecules. The third CoIIcentre forms part of a hexaaquacobalt(II) ion. In the crystal structure, there are two different one-dimensional chains, one being anionic and the other neutral, and adjacent chains are arranged in a cross-like fashion around the mid-point of the 4,4′-bipy ligands. The structure features O—H...O hydrogen-bonding interactions between sulfate anions and water molecules, resulting in a three-dimensional supramolecular network.

The novel title organic salt, 4C5H7N2+·C24H8O84−·8H2O, was obtained from the reaction of perylene-3,4,9,10-tetracarboxylic acid (H4ptca) with 4-aminopyridine (4-ap). The asymmetric unit contains half a perylene-3,4,9,10-tetracarboxylate (ptca4−) anion with twofold symmetry, two 4-aminopyridinium (4-Hap+) cations and four water molecules. Strong N—H...O hydrogen bonds connect each ptca4−anion with four 4-Hap+cations to form a one-dimensional linear chain along the [010] direction, decorated by additional 4-Hap+cations attached by weak N—H...O hydrogen bonds to the ptca4−anions. Intermolecular O—H...O interactions of water molecules with ptca4−and 4-Hap+ions complete the three-dimensional hydrogen-bonding network. From the viewpoint of topology, each ptca4−anion acts as a 16-connected node by hydrogen bonding to six 4-Hap+cations and ten water molecules to yield a highly connected hydrogen-bonding framework. π–π interactions between 4-Hap+cations, and between 4-Hap+cations and ptca4−anions, further stabilize the three-dimensional hydrogen-bonding network.

In the title one-dimensional coordination polymer, [Mn(NCS)3(C10H16N3)]n, the MnIIatom is coordinated by anN,N′-bidentate Schiff base and four thiocyanate ligands in a distorted octahedral N5S geometry. Bridging thiocyanate ligands interconnect adjacent [Mn(NCS)2(C10H16N3)] units, giving rise to helical chains extending along thebaxis. The chains are further linked through N—H...S hydrogen bonds, leading to a three-dimensional supramolecular network.

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.

Three new dicyanamide-bridged polymeric complexes of{[Mn(dca)2(L)2]·2H2O}n(1),{[Cd(dca)2(L)2]·2H2O}n(2), and{[Co(dca)2(L)2]2(L)}n(3) (dca = dicyanamide, L = pyridinium-4-olate) have been synthesized and structurally characterized. In the three compounds, the protons of hydroxyl groups of 4-hydroxypyridine transfer to pyridyl nitrogen atoms. Compounds1and2are isomorphous forming one-dimensional[M(dca)2(L)2]nchains where metals are connected by double dca anions. These one-dimensional chains are extended into two-dimensional layers through weak C–H⋯N hydrogen bonds. Further, these layers are assembled into a three-dimensional supramolecular network through N–H⋯O, O–H⋯O hydrogen bonds. Complex3is a coordination layer of (4, 4) topology with octahedral metal centers linked by four singleμ1,5-bridges. These layers are interlocked by N–H⋯O, O–H⋯O hydrogen bonds from coordinated water molecules and free L molecules, which leads to a three-dimensional supramolecular architecture. The variable temperature magnetic susceptibilities measurement of compounds1and3shows the existence of weak antiferromagnetic interactions between the metal centers. The thermogravimetric analyses of the compounds1–3are also discussed.

The transition metal squarates M(C4O4) · 4 H2O (M2+ = Mn2+, Fe2+, Co2+. Ni2+, and Zn2+) are isotypic. They crystallize monoclinically, space group Ce-Cf, and consist of one-dimensional chain molecules[xxx]with the chain axes alternatively in direction [110] and [110]. The transition metal is octahedrally coordinated by two oxygen atoms of two C4O42- -anions in rrarcs-position and 4 water molecules. Neighbouring chains are interlinked by hydrogen bonds. The distance between the planes of the parallel C4-rings of neighbouring chains is similar to the layer distance in graphite.

A new organic/inorganic salt formed by mixed-valence dibenzotetrathiafulvalene (DBTTF) radical cations and the spherical Keggin-type polyoxometalate anions [H3BW12O40]2− was obtained by electrochemical oxidation of the donor in an acetonitrile and a 1,2-dichloroethane solution containing the polyanion. The compound has been characterized by X-ray diffraction, elemental analysis, EPR, IR and Raman spectroscopy. X-Ray diffraction experiments have revealed that the compound consists of heteropolyanions, water molecules and DBTTF radical cations. The organic radicals form trimers and dimers via π-π stacking; moreover, the polyoxoanions and the organic donors are also held together by hydrogen bonding interactions. In their packing arrangement, a three-dimensional supramolecular network with one-dimensional channels along the b axis is established with uncoordinated water molecules residing in the channels.
