The asymmetric unit of the title salt, 2C12H28N+·SO4 2−·3H2O, contains two n-dodecylammonium cations, one sulfate anion and three water molecules. In the crystal, N—H...O hydrogen bonds link the cations and anions into layers parallel to (100). These layers are further connected through O—H...O hydrogen-bonding interactions involving the sulfate ions and the isolated water molecules. The three-dimensional structure can also be considered as the superposition of thin inorganic layers of SO4 2− anions and thick layers of alkylammonium cations perpendicular to the c axis.

The asymmetric unit of the title compound, [Ag3Yb(C5HN2O4)2(H2O)2]n, contains three AgIions, one YbIIIion, two imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The YbIIIatom is eight-coordinated, in a bicapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The two-coordinated AgIions exhibit three types of coordination environments. One AgIatom is bonded to two N atoms from two different imidazole-4,5-dicarboxylate ligands. The other two AgIatoms are each coordinated by one O atom and one N atom from two different imidazole-4,5-dicarboxylate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxylate ligands, generating a two-dimensional heterometallic layer. These layers are stacked along theaaxisviaO—H...O hydrogen-bonding interactions to generate a three-dimensional framework.

The structures of two hydrated salts of 4-aminophenylarsonic acid (p-arsanilic acid), namely ammonium 4-aminophenylarsonate monohydrate, NH4+·C6H7AsNO3−·H2O, (I), and the one-dimensional coordination polymercatena-poly[[(4-aminophenylarsonato-κO)diaquasodium]-μ-aqua], [Na(C6H7AsNO3)(H2O)3]n, (II), have been determined. In the structure of the ammonium salt, (I), the ammonium cations, arsonate anions and water molecules interact through inter-species N—H...O and arsonate and water O—H...O hydrogen bonds, giving the common two-dimensional layers lying parallel to (010). These layers are extended into three dimensions through bridging hydrogen-bonding interactions involving thepara-amine group acting both as a donor and an acceptor. In the structure of the sodium salt, (II), the Na+cation is coordinated by five O-atom donors, one from a single monodentate arsonate ligand, two from monodentate water molecules and two from bridging water molecules, giving a very distorted square-pyramidal coordination environment. The water bridges generate one-dimensional chains extending alongcand extensive interchain O—H...O and N—H...O hydrogen-bonding interactions link these chains, giving an overall three-dimensional structure. The two structures reported here are the first reported examples of salts ofp-arsanilic acid.

The title compound, 3C6H4N4O2S2·2C3H7NO·4H2O, comprises three 2,2′-disulfanylidene-5,5′-biimidazolidinylidene-4,4′-dione molecules, two dimethylformamide molecules and four water molecules arranged around a crystallographic inversion centre. The non-H atoms within the 5,5′-biimidazolidinylidene molecule are coplanar and these molecules aggregate through N—H...S hydrogen-bonding interactions with cyclic motifs [graph setR22(8)], giving two-dimensional ribbon structures which are close to being parallel. The two independent water molecules associate to form centrosymmetric cyclic hydrogen-bonded (H2O)4tetrameric units [graph setR44(8)]. The ribbon structures extend along theaaxis and are linked through the water tetramers and the dimethylformamide molecules by a combination of two- and three-centre hydrogen bonds, giving an overall three-dimensional structure.

The crystal structure of the title compound, C8H22N2 2+·2Cl−·H2O, exhibits layered stacking in which the organic cations are separated by inorganic layers containing the chloride anions and the water molecules. The diammonium octane chain straddles a centre of inversion and the single water of crystallization sits on a twofold rotation axis. The diammonium octane chains pack in parallel layers with every second hydrocarbon layer alternating in a staggered configuration with respect to the previous layer. The three-dimensional hydrogen-bonding network links the organic and inorganic layers together in a highly intricate and complex manner. The torsion angles of the hydrocarbon chain deviate from 180° as a result of hydrogen-bonding interactions to the water molecule and the surrounding chloride anions.

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 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.

A red block-shaped crystal of the title compound, [Co(HCOO)2(C12H10N4)2]n, was obtained by the reaction of cobalt(II) nitrate hexahydrate, formic acid and 1,1′-(1,4-phenylene)bis(1H-imidazole) (bib) molecules. The asymmetric unit consists of one CoIIcation, one formate ligand and two halves of a bib ligand. The central CoIIcation, located on an inversion centre, is coordinated by two carboxylate O atoms and four N atoms from bib ligands, completing an octahedral coordination geometry. The CoIIcentres are bridged by bib ligands, giving a two-dimensional net. Topologically, taking the CoIIatoms as nodes and the bib ligands as linkers, the two-dimensional structure can be simplified as a typicalsql/Shubnikov tetragonal plane network. The structure features C—H...O hydrogen-bonding interactions between formate and bib ligands, resulting in a three-dimensional supramolecular network.
