The structure of the title compound, [Cu4(CH3O)4(C11H13O2)4], consists of dimeric dinuclear copper(II) complexes oriented around a centre of inversion. Within each dinuclear fragment, the two CuIIatoms are in a distorted square-planar coordination sphere. Two neighbouring fragments are linked by four apical Cu—O contacts, yielding an overall square-pyramidal coordination environment for each of the four CuIIatoms. The molecules are arranged in layers parallel to (101). Non-classical C—H...O hydrogen-bonding interactions are observed between the layers.

The molecular structure of the title complex, [Ni(C13H8F2N2O)(C14H32P2)] or Ni(oFPU)(dippe), where oFPU is the dianion of bis(2-fluorophenyl)urea and dippe is 1,2-bis(di-isopropylphosphino)ethane, comprises an NiII atom with a distorted square-planar coordination environment (geometry index τ4 = 0.195). One of the fluorophenyl rings of the oFPU ligand is disordered over two sets of sites in an 0.832 (7):0.168 (7) ratio. The crystal structure displays C—H...O and C—H...F hydrogen-bonding interactions, leading to chains with R 2 2(12) motifs extending parallel to [100]. The title compound might be of interest with respect to the production of urea and carbamate derivatives of nickel(II).

In the centrosymmetric dinuclear title compound, [Pd2(C4H7)2(C16H14N2S2)], the metal atom is η3-coordinated by three C atoms of a crotyl ligand [Pd—C = 2.147 (4), 2.079 (5) and 2.098 (5) Å], the longest distance influenced by the steric interaction with the benzyl substituents of the dibenzyldithiooximidate (DTO) ligand. The Pd—N and Pd—S bonds to this ligand are 2.080 (3) and 2.3148 (9) Å, respectively, completing a square-planar coordination environment for PdII. The benzyl groups are oriented so as to maximize the interaction between a benzylic H atom and an S atom, resulting in a dihedral angle of 77.1 (2)° between the benzene rings and the metal complex plane. In the crystal, no inter-complex hydrogen-bonding interactions are present.

The complex crystallizes from 1:1 DMSO–acetonitrile as an acetonitrile solvate. In the crystal, weak C—H...O and C—H...N hydrogen-bonding interactions between adjacent complexes and between the acetonitrile solvent and the complex consolidate the packing.

In the title compound, [Cu(C9H6N3O2)2(C2H7N)2], the Cu2+ cation is situated on an inversion center and is coordinated by the N atoms of two dimethylamine ligands and the carboxylate O atoms of two 4-(1,2,4-triazol-1-yl)benzoate anions, leading to a slightly distorted square-planar N2O2 coordination environment. In the crystal, intermolecular N—H...N hydrogen bonds between the amine function and the central N atom of the triazole ring lead to the formation of ribbons parallel to [1\overline{1}1]. Weak intermolecular C—H...O hydrogen-bonding interactions are also observed that consolidate the crystal packing.

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].

In the title compound, [Re(C10H6NO2)(C7H11N)(CO)3], the ReIatom is coordinated by three carbonyl ligands in a facial arrangement and by the N, O and C atoms from a chelating quinaldate anion and a monodentate isocyanide ligand, respectively. The resultant C4NO coordination sphere is distorted octahedral. A lengthening of the axial Re—CO bondtransto the isocyanide ligand is indicative of thetranseffect. Individual complexes are stacked into rods parallel to [001] through displaced π–π interactions. Weak C—H...O hydrogen-bonding interactions between the rods lead to the formation of layers parallel to (010). These layers are stacked along [010] by C—H...H—C van der Waals contacts.

The title compound, [ReCl(pyAm)(CO)3], where pyAm is 1-[(pyridin-2-ylmethylidene)amino]adamantane (C16H20N2), was synthesized from the reaction of [ReCl(CO)5] and pyAm in an equimolar ratio. The ReIatom resides in an octahedral C3ClN2coordination sphere. The Re—C bondtransto the chloride ligand is noticeably longer compared to the other two Re—C distances. Weak C—H...Cl hydrogen-bonding interactions consoldiate the packing of the molecules. In this design, the pyAm ligand was employed due to its well-known pharmacokinetic properties.

The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2core [Cu...Cu distance = 2.7482 (11) Å], the CuIatoms of which are further coordinated by four molecules of acetonitrile. The CuIatom has an overall distorted tetrahedral coordination environment evidenced byL—Cu—Langles (L= N or I) ranging from 100.47 (10) to 117.06 (2)°. The coordination geometries of the acetonitrile ligands deviate slightly from linearity as shown by Cu—N—C angles of 167.0 (2) and 172.7 (2)°. In the crystal, there are no significant hydrogen-bonding interactions present, so the crystal packing seems to be formed predominantly by van der Waals forces.
