The structure of the title compound, {(NH4)2[Cu(C2O4)2]}n, at 100 K has monoclinic (P21/c) symmetry with the CuIIatom on an inversion center. The compound has a polymeric structure due to long Cu...O interactions which create [Cu(C2O4)2] chains along theaaxis. The structure also displays intermolecular N—H...O hydrogen bonding, which links these chains into a three-dimensional network.

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

The title compound, [Co2(L)2]3+·3NO3−[whereL= CH3C(CH2NHCH2CH2OH1/2)3], has been synthesized from the ligand 1,1,1-tris(2-hydroxyethylaminomethyl)ethane. The cobalt(III) dimer has an interesting and uncommon O—H...O hydrogen-bonding motif with the three bridging hydroxy H atoms each being equally disordered over two positions. In the dimeric trication, the octahedrally coordinated CoIIIatoms and the capping C atoms lie on a threefold rotation axis. The N atoms of two crystallographically independent nitrate anions also lie on threefold rotation axes. N—H...O hydrogen bonding between the complex cations and nitrate anions leads to the formation of a three-dimensional network structure. The compound is a racemic conglomerate of crystals containing either D or L molecules. The crystal used for this study is a D crystal.

The reaction of Co(NCS)2 with 3-(aminomethyl)pyridine as coligand leads to the formation of crystals of the title compound, [Co(NCS)2(C6H8N2)2] n , that were characterized by single-crystal X-ray analysis. In the crystal structure, the CoII cations are octahedrally coordinated by two terminal N-bonded thiocyanate anions as well as two pyridine and two amino N atoms of four symmetry-equivalent 3-(aminomethyl)pyridine coligands with all pairs of equivalent atoms in a trans position. The CoII cations are linked by the 3-(aminomethyl)pyridine coligands into layers parallel to the ac plane. These layers are further linked by intermolecular N—H...S hydrogen bonding into a three-dimensional network. The purity of the title compound was determined by X-ray powder diffraction and its thermal behavior was investigated by differential scanning calorimetry and thermogravimetry.

In the asymmetric unit of the title compound, C13H13N3O3, the 2-(2-methoxphenyl)ethenyl unit is connected to the methyl-nitroimidazole 1-methyl-4-nitro-1H-imidazole moiety. The molecule is quasi-planar and the planes of the two rings form a dihedral angle of 0.92 (11)°. The crystal packing can be described as layers parallel to the (011) plane, stabilized by intermolecular C—H...O hydrogen bonding, resulting in the formation of an infinite three-dimensional network linking these layers. Strong π–π stacking interactions are observed,viz.benzene–benzene, imidazole–imidazole and benzene–imidazole rings, with centroid–centroid distances of 3.528 (2), 3.457 (2) and 3.544 (2) Å, respectively. Intensity statistics indicated twinning by non-merohedry, with refined weighs of the twin components of 0.3687:0.6313.

In the structure of the title compound, [CdCl2(C4H8N2S)2], the CdIIatom is coordinated by two chloride ions and two 1,3-diazinane-2-thione (Diaz) molecules through their S atoms. The geometry around the CdIIatom is distorted tetrahedral, with bond angles in the range 101.55 (7)–117.91 (8)°. The CH2groups of one Diaz ligand are disordered over two sets of sites with an occupancy ratio of 0.711 (12):0.289 (12). The molecular structure is stabilized by intramolecular N—H...Cl hydrogen-bonding interactions, generating a butterflysynconformation. Intermolecular N—H...Cl and N—H...S interactions lead to the formation of a three-dimensional network structure. The structure has been determined from a crystal twinned by nonmerohedry, by a 180° rotation around the reciprocalcaxis. The twin ratio refined to 0.8866 (6):0.1134 (6).

The title compound I, C13H10N2O2S2, crystallizes in the monoclinic space group C2/c with eight molecules in the unit cell. Excluding for the ethyl substituent, the molecule of I adopts a nearly coplanar conformation (r.m.s. deviations is 0.058 Å), which is supported by the intramolecular C—H...O hydrogen-bonding interaction between the two ring systems [C...O = 2.859 (3) Å]. In the crystal, the molecules form dimeric associates via two bifurcated C—H...O hydrogen-bonding interactions between an ene hydrogen atom and a carbonyl functional group of an adjacent molecule [C...O = 3.133 (3) Å] and vice versa. The crystal structure is further stabilized by a three-dimensional network of weak hydrogen bonds between one molecule and six adjacent molecules as well as offset π–π stacking. The combination of the quinoxaline 2(1H)-one moiety with the dithiocarbonate moiety extends the aromaticity of the quinoxaline scaffold towards the substituent as well as influencing the π-system of the quinoxaline. The title compound is the direct precursor for a dithiolene ligand mimicking the natural cofactor ligand molybdopterin.

The asymmetric unit of the title compound, [Co(NCS)2(C6H6N2O)4]·2C6H6N2O·C2H5OH, comprises one CoIIcation, two thiocyanate anions, four coordinating and two solvent isonicotinamide molecules and one ethanol solvent molecule. The CoIIcations are octahedrally coordinated by four N-coordinating isonicotinamide ligands and two terminally N-bonded thiocyanate anions. These discrete complexes are linked by intermolecular N—H...O and N—H...S hydrogen-bonding interactions into a three-dimensional network. The two isonicotinamide and the ethanol solvent molecules are embedded in channels of this network and are linked through further N—H...O and N—H...N hydrogen bonds to the network. The ethanol solvent molecule is disordered over two sets of sites (occupancy ratio 0.6:0.4).

The asymmetric unit of the title compound, [Co(NCS)2(C6H6NS)4]·CH3OH, consists of one cobalt(II) cation, two thiocyanate anions, four pyridine-4-carbothioamide ligands and one methanol molecule that are located in general positions. The CoIIcations are coordinated by two terminal N-bonding thiocyanate anions and four N-bonding pyridine-4-carbothioamide ligands, resulting in discrete and slightly distorted octahedral complexes. These complexes are linked into a three-dimensional networkviaintermolecular N—H...S hydrogen bonding between the amino H atoms and the thiocyanate and pyridine-4-carbothioamide S atoms. From this arrangement, channels are formed in which the methanol solvate molecules are embedded and linked to the host structure by intermolecular O—H...S and N—H...O hydrogen bonding.
