Poly[[bis(acetonitrile-[kappa]N)bis[[mu]2-2,2'-(methylenedithio)bis(1,3,4-thiadiazole)-[kappa]2N4:N4']copper(II)] bis(perchlorate) acetonitrile solvate]

Abstract top

In the title compound, {[Cu(C5H4N4S4)2(C2H3N)2](ClO4)2·C2H3N}n, the CuII atom occupies a crystallographic inversion centre and is six-coordinated by six N atoms of four symmetry-related 2,2'-(methylenedithio)bis(1,3,4-thiadiazole) (L) ligands and two acetonitrile molecules in a slightly distorted octahedral geometry. The ligand L adopts an N:N'-bidentate bridging mode in a trans configuration, bridging the Cu atoms via translation symmetry, forming a two-dimensional layer-like structure. The perchlorate ions serve as acceptors for intermolecular C-H...O hydrogen bonds, which link the layers into a three-dimensional network. The ClO4- anion is disordered with an occupation ratio of 0.658:0.342.

Comment top

The asymmetric unit of the title compound consists of half a CuII atom, two independent 2,2'-(methylenedithio)bis(1,3,4-thiadiazole) (L) ligands, one coordinated acetonitrile molecule, one uncoordinated acetonitrile molecule, and one perchlorate ion (Fig. 1). The CuII atom is coordinated by six N atoms, from four L ligands and two acetonitrile molecules, in a slightly distorted octahedral geometry. All six Cu—N bond distances are within the range expected for such coordination bonds (Huang et al., 2009; Wang et al., 2008; Qin et al., 2009). The ligand L adopts a N:N'-bidentate bridging mode in trans configuration, so bridging the copper atoms via translation symmetry to form a two-dimensional layer-like structure, with a bridging Cu···Cu distance of 10.6661 (8) Å (Fig. 2). The centroid-centroid separation and dihedral angle of the thiadiazole rings are 6.3928 (5) Å and 81.86 (13)°, respectively.

In the crystal structure the region between the layes is taken up by perchlorate ions and uncoordinated acetonitrile molecules. The perchlorate ions serve as acceptors for C—H···O hydrogen-bonds, which link the chains into a three-dimensional network (Table 1 and Fig. 3).

Experimental top

The reaction of 2,2'-(methylenedithio)bis(1,3,4-thiadiazole) (0.2 mmol) with Cu(ClO4)2 (0.1 mmol) in an acetonitrile solution (20 ml) afforded a light blue solid after a few minutes. It was filtered off, washed with acetone, and dried in air. Single crystals, suitable for X-ray analysis, were obtained by slow diffusion of Et2O into an acetonitrile solution of the solid.

Refinement top

All H-atoms were positioned geometrically and treated as riding: C—H = 0.93 - 09.7 Å with Uiso(H) = 1.2 or 1.5Ueq(parent C-atom).
