The structure of the title compound, [Cu2Cl2(C12H10N2)] n , shows that each CuI ion is tetrahedral, being coordinated by three Cl atoms and one N atom of the 1,2-bis(4-pyridyl)ethene ligand (BPE, C12H10N2). Cl atoms and BPE molecules bridge the CuI ions to form a two-dimensional layer structure through inversion centres located at the mid-point of the Cu2Cl2 bridge and at the mid-point of the C=C double bond of the BPE ligand.

VIVoxyfluorides are of interest as frustrated magnets. The successful synthesis of two-dimensionally connected vanadium(IV) oxyfluoride structures generally requires the use of ionic liquids as solvents. During solvothermal synthesis experiments aimed at producing two- and three-dimensional vanadium(IV) selenites with triangular lattices, the title compound, diaquatetra-μ-fluorido-dioxidodivanadium(IV) monohydrate, V2O2F4(H2O)2·H2O, was discovered and features a new infinite V4+-containing two-dimensional layer comprised of fluorine-bridged corner- and edge-sharing VOF4(H2O) octahedral building units. The synthesis was carried out under solvothermal conditions. The V4+centre exhibits a typical off-centring, with a short V=O bond and an elongatedtrans-V—F bond. Hydrogen-bonded water molecules occur between the layers. The structure is related to previously reported vanadium oxyfluoride structures, in particular, the same layer topology is seen in VOF3.

Hydrazones and their derivatives are closely related to imine compounds and are potential antimicrobial agents. They have also found application in supramolecular chemistry as multitopic ligands to link multiple metal centres for the design of hybrid molecular frameworks. The molecule of the title compound, C6H8N4, consists of an imine linkage with an N—N bond length of 1.3540 (14) Å. This asymmetric compound is nearly planar and adopts an E configuration about the azomethine C=N double bond. In the solid state, there are two intermolecular N—H...N interactions that interconnect the molecules into a two-dimensional network. The three-dimensional arrangement of the crystal packing is further stabilized by intermolecular π–π interactions interconnecting the centroids of the heterocyclic rings.

A Chain

In the title compound, [Pb(C8H4O4)(C24H16N2)] n , the benzene-1,4-dicarboxylate (1,4-BDC) dianions link the PbII atoms to form a chain structure. The PbII atom is coordinated by 4,7-diphenyl-1,10-phenanthroline (L) and is also bonded to four 1,4-BDC O atoms, resulting in a very distorted cis-PbN2O4 octahedron. There are two 1,4-BDC half-anions in the asymmetric unit, both completed by inversion. Aromatic π–π stacking between L ligands in adjacent chains results in a two-dimensional supramolecular layer structure [minimum centroid–centroid separation 3.464 (5) Å].

In the title compound, {[Cu2(μ4-C5H6O4)2(μ2-C14H16N2)]·2CH3CN}n, the Cu2dinuclear units are connected by glutartate ligands, forming one-dimensional double chains. These chains, are in turn bridged by 1,4-bis(pyridin-4-yl)butane ligands to form a two-dimensional layer structure parallel to (112). The carboxylate groups of the glutarate ligand bridge two copper(II) ions, forming a paddle-wheel-type Cu2(CO2)4dinuclear secondary building unit. A crystallographic inversion centre is located midway between two CuIIions, with a Cu...Cu distance of 2.639 (3) Å. The coordination geometry of the unique CuIIion is slightly disorted square pyramidal, formed by four equatorial carboxylate O atoms and an axial pyridyl N atom.

The title compound, [HgCl2(C4H5N3)]n, features a two-dimensional network parallel to (001) that is based on an HgIIatom octahedrally coordinated by four μ2-Cl atoms and two μ2-2-aminopyrimidine (apym) ligands intranspositions, yielding a distorted HgCl4N2octahedron. The coordination network can be described as an uninodal 4-connected net with the sql topology. The HgIIion lies on a site of -1 symmetry and the apym ligand lies on sites ofmsymmetry with the mirror plane perpendicular to the pyrimidine plane and passing through the NH2group N atom. This polymeric structure is stabilized by N—H...Cl hydrogen bonds and columnar π–π stacking of pyrimidine rings, with a centroid–centroid distance of 3.832 (2) Å.
