The title complex, chlorobis{ethyl N-[(4-methylanilino)thiocarbonyl]carbamate-κS}copper(I), [CuCl(C11H14N2O2S)2], was synthesized by the reaction of cupric chloride with the corresponding thiourea derivative. The complex has imposed crystallographic m symmetry and the CuI coordination environment is trigonal planar, formed by two S atoms and one Cl atom. The formation of intramolecular hydrogen bonds promotes the stability of the complex.

In the title complex, [Sn2(CH3)4(C8H6N2O4)2(CH4O)2], each SnIV ion exists in a distorted pentagonal–bipyramidal coordination environment, coordinated by three O atoms and one N atom from the pyruvic acid 2-furoic acid hydrazone ligands, one O atom from a methanol molecule and two axial C atoms from trans methyl groups, thus forming a dimeric molecule, which has crystallographic \overline{1} symmetry. In the dimeric structure there are also intramolecular hydrogen bonds, which contribute to the crystal stability and compactness.

In the title CuIIcomplex, [Cu(C19H14O3P)2(C3H7NO)(H2O)2], the molecule is bisected by a twofold axis relating the two 2-(diphenylphosphoryl)benzoate (ODPPB) ligands. The asymmetric unit consists of a CuIImetal centre on the symmetry axis, an ODPPB ligand, one water ligand and one dimethylformamide (DMF) ligand (disordered around the twofold axis). The CuIIion has fivefold coordination provided by two carboxylate O atoms from two ODPPB ligands, two O atoms from two coordinated water molecules and another O atom from a (disordered) DMF molecule, giving a CuO5square-pyramidal coordination geometry. The ODPPB ligand adopts a terminal monocoordinated mode with two free O atoms forming two strong intramolecular hydrogen bonds with the coordinated water molecules, which may play a key role in the stability of the molecular structure, as shown by the higher release temperature for the coordinated water molecules than for the coordinated DMF molecule. The optical absorption properties of powder samples of the title compound have also been studied.

In the title complex, chloridotetrakis(1H-imidazole-κN3)cobalt(II) chloride, [CoCl(C3H4N2)4]Cl, the CoIIcation has a distorted square-pyramidal coordination environment. It is coordinated by four N atoms of four imidazole (Im) groups in the basal plane, and by a Cl atom in the apical position. It is isostructural with [Cu(Im)4Cl]Cl [Morzyk-Ociepaet al.(2012).J. Mol. Struct.1028, 49–56] and [Cu(Im)4Br]Br [Hossaini Sadret al.(2004).Acta Cryst. E60, m1324–m1326]. In the crystal, the [CoCl(C3H4N2)4]+cations and Cl−anions are linkedviaN—H...Cl hydrogen bonds, forming layers parallel to (010). These layers are linkedviaC—H...Cl hydrogen bonds and C—H...π and π–π [inter-centroid distance = 3.794 (2) Å] interactions, forming a three-dimensional framework. The IR spectrum shows vibrational bands typical for imidazol groups. The monoclinic unit cell of the title compound emulates an orthorhombic cell as its β angle is close to 90°. The crystal is twinned, with the refined ratio of twin components being 0.569 (1):0.431 (1).

The title complex, [Cu2(C20H16F2N4O2)(CH4O)2](ClO4)2, was synthesized by cyclo-condensation between ethylenediamine and 2,6-diformyl-4-fluorophenol in the presence of CuII ions. This dinuclear copper complex is centrosymmetric. Both Cu atoms are in a distorted tetrahedral geometry, coordinated by three O atoms and two N atoms. The two Cu atoms are bridged by two endogenous phenol O atoms, with a Cu...Cu distance of 2.8998 (7) Å. In the crystal structure, the perchlorate ions link the macrocycles through inter- and intramolecular hydrogen bonds.

The molecular structure of the tetrakis(triphenylphosphanyl)disilver salt of butane-1,1,4,4-tetracarboxylic acid, [Ag2(C8H8O8)(C18H15P)4]·3CH2Cl2, crystallizes with one and a half molecules of dichloromethane in the asymmetric unit. The coordination complex exhibits an inversion centre through the central CH2—CH2bond. The AgIatom has a distorted trigonal–planar P2O coordination environment. The packing is characterized by intermolecularT-shaped π–π interactions between the phenyl rings of the PPh3substituents in neighbouring molecules, forming a ladder-type superstructure parallel to [010]. These ladders are arranged in layers parallel to (101). Intramolecular hydrogen bonds between the OH group and one O atom of the Ag-bonded carboxylate group results in an asymmetric bidendate coordination of the carboxylate moiety to the AgIion.
