The title salt, [Co(C8H4F3O3)(C12H8N2)(H2O)3](C8H4F3O3), was obtained under solvothermal conditions by the reaction of 2,4,5-trifluoro-3-methoxybenzoic acid with CoCl2in the presence of 1,10-phenanthroline (phen). The CoIIion is octahedrally coordinated by two N atoms [Co—N = 2.165 (2) and 2.129 (2) Å] from the phen ligand, by one carboxylate O atom [Co—O = 2.107 (1) Å] and by three O atoms from water molecules [Co—O = 2.093 (1), 2.102 (1) and 2.114 (1) Å]. The equatorial positions of the slightly distorted octahedron are occupied by the N atoms, the carboxylate O and one water O atom. An intra- and intermolecular O—H...O hydrogen-bonding network between the water-containing complex cation and the organic anion leads to the formation of ribbons parallel to [010].

In the crystal structure of the title compound, 2C5H6N5 +·C6Cl2O4 2−·2H2O, two adeninium cations, one chloranilate dianion and two water molecules are held together by O—H...O, N—H...O, O—H...Cl and C—H...O hydrogen bonds, forming a centrosymmetric unit. The chloranilate dianion resides on an inversion centre. The anion and two cations are approximately coplanar, the dihedral angle between the planes of the adeninium cation and the chloranilate dianion being 3.25 (3)°. The crystal structure is stabilized by inter-unit N—H...N, N—H...O, N—H...Cl and O—H...N hydrogen bonds, forming a three-dimensional hydrogen-bonding network.

The crystal structure of thomsenolite, NaCaAlF6•H2O, has been redetermined to establish the hydrogen-bonding scheme in this mineral. Both hydrogen atoms participate in branched [Formula: see text] bonds. The hydrogen bonds link the AlF6, octahedra to form infinite chains ||b, which in turn are cross-linked to form infinite double sheets {[AlF6] + Ca}—(H2O)—{[AlF6] + Ca}||(001). The Na atoms are located exclusively in layers ||(001) which separate the double sheets. A detailed comparison of thomsenolite with its dimorph, pachnolite, shows that the structure of pachnolite is obtained in essence by interchanging the positions of one half of the Na atoms and one half of the water molecules in thomsenolite. The two-dimensional, layerlike hydrogen-bonding network in thomsenolite is thereby changed to one of a three-dimensional character in pachnolite. Other features of the two structures, including the Al—F and [Formula: see text] distances, are compared and discussed in some detail.

The structure of the title compound, [Re2Cl6(C3H7NO2)2]·1.5H2O, comprises a dinuclear complex cation [Re—Re = 2.2494 (3) Å] involvingcis-oriented double carboxylate bridges, four equatorial chloride ions and two weakly bonded chloride ligands in the axial positions at the two rhenium(III) atoms. In the crystal, two complex molecules and two water molecules constitute hydrogen-bonded dimers, while an extensive hydrogen-bonding network involving the groups of the zwitterionic ligand is important for generation of the framework. An additional partially occupied water molecule is disordered over two sets of sites about a symmetry centre with a site-occupancy ratio of 0.3:0.2.

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 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.

The title compound, ammonium catena-[monoboro-monodihydrogendiborate-monohydrogenphosphate] hemihydrate, was obtained under solvothermal conditions using glycol as the solvent. The crystal structure is constructed of one-dimensional infinite borophosphate chains, which are interconnected by ammonium ions and water molecules via a complex hydrogen-bond network to form a three-dimensional structure. The water molecules of crystallization are disordered over inversion centres, and their H atoms were not located.

The crystal structure of the title compound, C2H10N2 2+·C6H2O4S2−·2H2O, is built of ethylenediammonium dications, occupying a special position on an inversion center, thiophene-2,5-dicarboxylate dianions, in a special position on the twofold axis, and water molecules in general positions. All residues are involved in an extensive hydrogen-bonding system, which links them into a three-dimensional supramolecular arrangement.

AbstractThe crystal structure of Ni-rich gordaite–thérèsemagnanite has been determined from a sample collected at pillar 80 in the North mine, Cap Garonne, Var, France. The structure was refined to R1 = 0.0693 for 935 reflections with I > 2σ(I). The mineral is isostructural with gordaite, forming a layered structure with an extensive hydrogen-bonding network. The possible polytypic relationship between gordaite, thérèsemagnanite and guarinoite is also discussed. The guarinoite formula (Zn,Co,Ni)6(SO4)(OH,Cl)10·5H2O is also likely to be incorrect and is more likely to be Na(Zn,Co)4(SO4)(OH)6Cl·5–6H2O, meaning that guarinoite is equivalent to Co-rich gordaite-2H and would not be a distinct mineral species.

The title compound, [Cu(C12H8N3O2)(N3)(H2O)], was formed by the air oxidation of 2-(aminomethyl)pyridine in 95% ethanol in the presence of copper(II) nitrate and sodium azide with condensation of the resulting picolinamide molecules to generate the imide moiety. The CuIIion has a square-pyramidal coordination sphere, the basal plane being occupied by four N atoms [two pyridine (py) N atoms, the imide N atom and an azide N atom] in a nearly planar array [mean deviation = 0.048 (6) Å] with the CuIIion displaced slightly from the plane [0.167 (5) Å] toward the fifth ligand. The apical position is occupied by a coordinating water molecule [Cu—O = 2.319 (4) Å]. The crystal structure is stabilized by hydrogen-bonding interactions between the water molecules and carbonyl O atoms. The inversion-related square-pyramidal complex molecules pack base-to-base with long Cu...Npycontact distances of 3.537 (9) Å, preventing coordination of a sixth ligand.
