The title compound, [Ni(SO4)(C18H12N6)(H2O)2]·2H2O, is isostructural with the zinc and cobalt analogues already reported in the literature. The compound is monomeric, with an octahedral Ni centre coordinated by a tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine ligand, two water molecules and a monodentate sulfate ligand. The presence of two additional water molecules of crystallization leads to a total of eight hydrogen-bond donors, from which a very complex hydrogen-bonding scheme is built up.

In the title compound, [Cu(C11H10N3O)2(C8H4O5)2]·4H2O, the CuIIion, located on a crystallographic inversion center, is coordinated in a square-planar environment by twotrans-O atoms belonging to two monodentate 5-hydroxyisophthalate (hip) dianions and twotransnicotinamide pyridyl N-donor atoms from monodentate protonated pendantN-(pyridin-4-yl)nicotinamide (4-pnaH) ligands. The protonated 4-pyridylamine groups engage in N—H+...O−hydrogen-bond donation to unligated hip O atoms to construct supramolecular chain motifs parallel to [100]. Water molecules of crystallization, situated between the chains, engage in O—H...O hydrogen bonding to form supramolecular layers and the overall three-dimensional network structure.

The title compound, [Gd(C4H9NO)4(H2O)3][Fe(CN)6]·2H2O, is a bimetallic complex containing two isolated metal complexes. The Fe atom is bonded to six cyano ligands forming an almost ideal octahedron. One of the cyano groups is also connected through a hydrogen bond to a water molecule bonded to the Ga atom. Aside from three water molecules, gadolinium is also coordinated by four dimethylacetamide molecules, two of which show various degrees of structural disorder. The asymmetric unit also includes two solvent water molecules, which take part in hydrogen bonding, forming an extended network.

An intermolecular N—H...O hydrogen bond is also observed.

The title compound has been prepared from Re(CO)5Br by a bromide-abstraction reaction with silver fluoride. It completes the series of known halide clusters of the type [Re(CO)3X]4 (where X = halide). The crystals are tetragonal, space group 14, with a 11.716(5), c 8.988(3) �, and Z 2. The structure was refined by full-matrix least-squares to an R value of 0.027 for 1380 observed reflections. The molecules are cubane-type clusters of Re(CO)3 groups at one set of corners interpenetrated with fluorine atoms at the other set. The clusters exhibit the molecular symmetry 43m. Each of the fluorine atoms is involved in μ3 type bridging with the rhenium atoms at an average bonding distance of 2.200(5) �. The clusters are held together by hydrogen bonding of fluoride to water molecules.

In the structure of the brucinium salt of 4-aminophenylarsonic acid (p-arsanilic acid), systematically 2,3-dimethoxy-10-oxostrychnidinium 4-aminophenylarsonate tetrahydrate, (C23H27N2O4)[As(C6H7N)O2(OH)]·4H2O, the brucinium cations form the characteristic undulating and overlapping head-to-tail layered brucine substructures packed along [010]. The arsanilate anions and the water molecules of solvation are accommodated between the layers and are linked to them through a primary cation N—H...O(anion) hydrogen bond, as well as through water O—H...O hydrogen bonds to brucinium and arsanilate ions as well as bridging water O-atom acceptors, giving an overall three-dimensional network structure.

The asymmetric unit of the title compound, C10H9N2 +·0.5C2O4 2−·C2H2O4·H2O, consists of a 2,2′-bipyridinium cation, half an oxalate dianion, one oxalic acid and one water molecule. One N atom in 2,2′-bipyridine is unprotonated, while the second is protonated and forms an N—H...O hydrogen bond. In the crystal, the anions are connected with surrounding acid molecules and water molecules by strong near-linear O—H...O hydrogen bonds. The water molecules are located between the anions and oxalic acids; their O atoms participate as donors and acceptors, respectively, in O—H...O hydrogen bonds, which form sheets arranged parallel to the ac plane.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.

Distorted Octahedral

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.
