The title mononuclear CuIIcomplex, [Cu(C8H5O3)2(C10H8N2)], is comprised of a CuIIcation, two 4-formylbenzoate (L−) ligands and a 2,2′-bipyridine (bipy) ligand. The CuIIion and bipy ligand lie on a crystallographic twofold rotation axis; the CuIIion is coordinated by two N atoms from one bipy ligand and two O atoms from two different carboxylate groups of twoL−ligands, exhibiting effectively a distorted square-planar geometry. The complex molecules are interlinked to generate two-dimensional supramolecular layers in theabplane, formed by C—H...O hydrogen bonds, where the O acceptor is the O atom from the carboxylate group not involved in coordination to the CuIIion. The two-dimensional layers are stacked in a sequenceviaC—H...O hydrogen-bonding interactions where the formyl O atom acts as acceptor.

The title compound, [Pd(SC6H4F-p)Cl(PPh3)2]·0.5CH3OH, features a PdIIcomplex with two triphenylphosphane (PPh3) ligands arranged in atransconformation, with one chloride and one 4-fluorobenzenethiolate ligand completing the coordination sphere, giving rise to a slightly distorted square-planar geometry of the PdIIion. The methanol solvent molecule is disordered about an inversion centre with an occupancy of 0.25 for each molecule. In the crystal, weak C—H...Cl hydrogen-bonding interactions between the complex molecules generate chain frameworks parallel to [010].

The title compound, {[Cu(NH3)4][Cu(CN)3]2}n, features a CuI–CuIImixed-valence CuCN framework based on {[Cu2(CN)3]−}nanionic layers and [Cu(NH3)4]2+cations. The asymmetric unit contains two different CuIions and one CuIIion which lies on a centre of inversion. Each CuIion is coordinated to three cyanide ligands with a distorted trigonal–planar geometry, while the CuIIion is ligated by four ammine ligands, with a distorted square-planar coordination geometry. The interlinkage between CuIions and cyanide bridges produces a honeycomb-like {[Cu2(CN)3]−}nanionic layer containing 18-membered planar [Cu(CN)]6metallocycles. A [Cu(NH3)4]2+cation fills each metallocyclic cavity within pairs of exactly superimposed {[Cu2(CN)3]−}nanionic layers, but there are no cations between the layers of adjacent pairs, which are offset. Pairs of N—H...N hydrogen-bonding interactions link the N—H groups of the ammine ligands to the N atoms of cyanide ligands.

In the title compound, [Cd(C13H11IN3O2)2]·2CH3OH, which crystallizes withZ= 4 in the space groupPbcn, the CdIIatom is located on a twofold rotation axis and coordinated by two I−anions and two N atoms from the pyridine rings of the twoN′-[(E)-4-hydroxybenzylidene]pyridine-4-carbohydrazide ligands. The geometry around the CdIIatom is distorted tetrahedral, with bond angles in the range 94.92 (11)–124.29 (2)°. The iodide anions undergo intermolecular hydrogen-bonding contacts with the C—H groups of the organic ligands of an adjacent complex molecule, generating a chain structure along thebaxis. Furthermore, an extensive series of O—H...O, N—H...O and C—H...O hydrogen-bonding interactions involving both the complex molecules and the ethanol solvate molecules generate a three-dimensional network.

Supramolecular Arrangements

Trinuclear copper–pyrazolate entities are present in various Cu-based enzymes and nanojar supramolecular arrangements. The reaction of copper(II) chloride with pyrazole (pzH) and sodium benzoate (benzNa) assisted by microwave radiation afforded a neutral centrosymmetric hexanuclear copper(II) complex, [Cu6(C7H5O2)4(OH)2(C3H3N2)6(C2H5OH)2]·2C2H5OH. Half a molecule is present in the asymmetric unit that comprises a [Cu3(μ3-OH)(pz)3]2+ core with the copper(II) atoms arranged in an irregular triangle. The three copper(II) atoms are bridged by an O atom of the central hydroxyl group and by three bridging pyrazolate ligands on each of the sides. The carboxylate groups show a chelating mode to one and a bridging syn,syn mode to the other two CuII atoms. The coordination environment of one CuII atom is square-planar while it is distorted square-pyramidal for the other two. Two ethanol molecules are present in the asymmetric unit, one binding to one of the CuII atoms, one as a solvent molecule. In the crystal, stabilization arises from intermolecular O—H...O hydrogen-bonding interactions.

In the title salt (C7H11N2)2[Cu(C4N2S2)2], the Cu2+ ion is coordinated by four S atoms of two 1,2-dicyanoethene-1,2-dithiolate (or maleonitriledithiolate, mnt2−) ligands in an approximate square-planar geometry. The Cu atom is located on an inversion centre. Strong hydrogen-bonding interactions between the pyridinium proton and the CN groups of the mnt2− ligand link anions and cations into a one-dimensional chain structure.

The reaction of NiIIacetate tetrahydrate with the ligand 4-phenyl-2-(1,2,3,4-tetrahydronaphthalen-1-ylidene)hydrazinecarbothioamide in a 2:1 molar ratio yielded the title compound, [Ni(C16H16N3S)2]·2C4H8O·H2O. The deprotonated ligands act asN,S-donors, forming five-membered metallacycles with the metal ion exhibiting aciscoordination mode unusual for thiosemicarbazone complexes. The NiIIion is four-coordinated in a tetrahedrally distorted square-planar geometry.Trans-arranged anagostic C—H...Ni interactions are observed. In the crystal, the complex molecules are linked by water molecules through N—H...O and O—H...S hydrogen-bonding interactions into centrosymmetric dimers stacked along thecaxis, forming rings of graph-setR44(12). Classical O—H...O hydrogen bonds involving the water and tetrahydrofuran solvent molecules as well as weak C—H...π interactions are also present.
