The title compound, C2H10N2 2+·C7H3NO4 2−·2H2O, forms a three-dimensional hydrogen-bonded framework structure in which both of the amine groups of ethylenediamine are protonated and participate in a total of six hydrogen-bonding interactions with carboxylate O-atom acceptors of the anions as well as the water molecules. The cations lie on crystallographic inversion centres and adopt extended conformations, while the anions have twofold rotational symmetry. This results in the pyridine N atom and its ortho-related CH group being disordered over two 50% occupancy sites.

In the title complex, [Ni(C12H9N2O3S)2(H2O)2]·4H2O, the NiII ion is coordinated by four N atoms from two bidentate chelating 4-[(pyridin-2-yl)methylideneamino]benzenesulfonate ligands and two O atoms from cis-related water molecules in a slightly distorted octahedral environment [Ni—N = 2.071 (3)–2.121 (3) Å and Ni—O = 2.071 (2) and 2.073 (3) Å]. In the crystal, the coordinated water molecules and the four water molecules of solvation are involved in intermolecular O—H...O hydrogen-bonding interactions with water and sulfonate O-atom acceptors, giving a three-dimensional framework structure.

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.

Form Part

The title compound, {[Zn4(C8H4O4)3(OH)2(C12H6N2O2)2]·2H2O}n, has been prepared hydrothermally by the reaction of Zn(NO3)2·6H2O with benzene-1,4-dicarboxylic acid (H2bdc) and 1,10-phenanthroline-5,6-dione (pdon) in H2O. In the crystal structure, a tetranuclear Zn4(OH)2fragment is located on a crystallographic inversion centre which relates two subunits, each containing a [ZnN2O4] octahedron and a [ZnO4] tetrahedron bridged by a μ3-OH group. The pdon ligand chelates to zinc through its two N atoms to form part of the [ZnN2O4] octahedron. The two crystallographically independent bdc2−ligands are fully deprotonated and adopt μ3-κO:κO′:κO′′ and μ4-κO:κO′:κO′′:κO′′′ coordination modes, bridging three or four ZnIIcations, respectively, from two Zn4(OH)2units. The Zn4(OH)2fragment connects six neighbouring tetranuclear units through four μ3-bdc2−and two μ4-bdc2−ligands, forming a three-dimensional framework with uninodal 6-connected α-Po topology, in which the tetranuclear Zn4(OH)2units are considered as 6-connected nodes and the bdc2−ligands act as linkers. The uncoordinated water molecules are located on opposite sides of the Zn4(OH)2unit and are connected to it through hydrogen-bonding interactions involving hydroxide and carboxylate groups. The structure is further stabilized by extensive π–π interactions between the pdon and μ4-bdc2−ligands.

The non-H atoms in the organic component of the title compound, C8H7N3OS2·H2O, are almost coplanar, as the dihedral angle between the two ring planes is only 1.8 (2)°; there is a wide C—C—C angle of 127.8 (3)° at the methine C atom linking the two rings. The molecular components are linked into a three-dimensional framework structure by two-centre hydrogen bonds of N—H...O and O—H...N types, together with a three-centre O—H...(N,S) system. Comparisons are made with some (Z)-5-arylmethylidene-2-sulfanylidene-1,3-thiazolidin-4-ones.

The title compound, (C21H20OP)(C19H15N4)[CuCl4], was obtained by reacting CuCl2·2H2O with a mixture of one equivalent of acetonyltriphenylphosphonium chloride and one equivalent of 2,3,5-triphenyltetrazolium chloride in acetonitrile. In the structure, the Cu centre in the dianion is bonded to four chloride ligands and adopts a distorted tetrahedral geometry. The phosphonium cation likewise adopts the expected tetrahedral geometry. The tetrazolium ring forms dihedral angles of 77.68 (10), 26.85 (11) and 66.48 (10)° with the planes of the benzene rings of the substituent groups. In the crystal, weak C—H...Cl hydrogen-bonding interactions involving both cations and the anion give rise to a three-dimensional supramolecular structure.

In the title compound, (C6H8N4)[AuCl4]Cl, the 4,4′-bi(1H-pyrazol-2-ium) dication, denoted [H2bpz]2+, is situated across a centre of inversion, the [AuCl4]−anion lies across a twofold axis passing through Cl—Au—Cl, and the Cl−anion resides on a twofold axis. Conventional N—H...Cl hydrogen bonding [N...Cl = 3.109 (3) and 3.127 (3) Å, and N—H...Cl = 151 and 155°] between [H2bpz]2+cations (square-planar node) and chloride anions (tetrahedral node), as complementary donors and acceptors of four hydrogen bonds, leads to a three-dimensional binodal four-connected framework with cooperite topology (three-letter notation pts). The framework contains channels along thecaxis housing one-dimensional stacks of square-planar [AuCl4]−anions [Au—Cl = 2.2895 (10)–2.2903 (16) Å; interanion Au...Cl contact = 3.489 (2) Å], which are excluded from primary hydrogen bonding with the [H2bpz]2+tectons.
