The title compound, bis(1,2-diphenyl-2-sulfanylideneethanethiolato-κ2 S,S′)(1,3,5-triaza-7-phosphaadamantane-κP)cobalt(II) dichloromethane hemisolvate, [Co(pdt)2(PTA)]·0.5C2H4Cl2 or [Co(C14H10S2)2(C6H12N3P)]·0.5C2H4Cl2, contains two phenyldithiolene (pdt) ligands and a 1,3,5-triaza-7-phosphaadamantane (PTA) ligand bound to cobalt with the solvent 1,2-dichloroethane molecule located on an inversion center. The cobalt core exhibits an approximately square-pyramidal geometry with partially reduced thienyl radical monoanionic ligands. The supramolecular network is consolidated by hydrogen-bonding interactions primarily with nitrogen, sulfur and chlorine atoms, as well as parallel displaced π-stacking of the aryl rings. The UV–vis, IR, and CV data are also consistent with monoanionic dithiolene ligands and an overall CoII oxidation state.

In the title compound, [Mn(C44H28N4)Cl]·2C5H6N2, the MnIIIcentre is coordinated by four pyrrole N atoms [averaged Mn—N = 2.012 (4) Å] of the tetraphenylporphyrin molecule and one chloride axial ligand [Mn—Cl = 2.4315 (7) Å] in a square-pyramidal geometry. The porphyrin macrocycle exhibits a non-planar conformation with majorrufflingandsaddlingdistortions. In the crystal, two independent solvent molecules form dimers through N—H...N hydrogen bonding. In these dimers, one amino N atom has a short Mn...N contact of 2.642 (1) Å thus completing the Mn environment in the form of a distorted octahedron, and another amino atom generates weak N—H...Cl hydrogen bonds, which link further all molecules into chains along theaaxis.

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.

Amine Function

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.

In the title compound, [Cu(C11H7Br2NO5)(C3H7NO)(H2O)]·C3H7NO·H2O, the CuII atom is coordinated in a slightly distorted square-pyramidal geometry defined by two O atoms and one N atom from a 3-carboxy-2-(3,5-dibromo-2-oxidobenzylamino)propanoate ligand, one O atom from a dimethylformamide (DMF) molecule in the basal plane, and by one O atom from an aqua ligand in the apical position. In the crystal structure, the water molecules are linked by O—H...O hydrogen bonds into chains which resemble a pearl necklace. The molecules form a three-dimensional supramolecular network through O—H...O hydrogen bonds and C—H...Br hydrogen bonds.

The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by anO-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated CuIatoms are bridged by two μ2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu...Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8 Å), excluding a significant cupriophilic interaction in the actual dimer. C—H...O and C—H...I hydrogen bonding interactions as well as C—H...π(aryl) interactions stabilize the three-dimensional supramolecular network.

The 2-methyl-5-nitrobenzenesulfonate anions do not coordinate to the magnesium, but act as counter-anions. The crystal structure is composed of alternating layers of [Mg(H2O)6]2+ cations and anions. The [Mg(H2O)6]2+ cations, water molecules and anions are connected through a complex pattern of hydrogen-bonding interactions, resulting in a three-dimensional supramolecular network.
