title: Crystal structure of bis-[1,3,4,5-tetra-methyl-1H-imidazole-2(3H)-thione-κS]chlorido-copper(I).
abstract: The mol-ecular structure of the title compound, [CuCl(C7H12N2S)2], shows a slightly distorted trigonal-planar coordination geometry of the Cu atom. The Cu-Cl bond measures 2.2287 (9) Å, and the two Cu-S bonds are significantly different from each other, with values of 2.2270 (10) and 2.2662 (10) Å. Also, the S-Cu-Cl angles differ, with values of 113.80 (4) and 124.42 (4)°, while the S-Cu-S angle is 121.51 (4)°. The two imidazole rings are almost parallel, making a dihedral angle of 2.1 (2)°. In the crystal, the shortest C-H⋯Cl interactions stabilize a three-dimensional network with molecules linked into centrosymmetric dimers that are stacked along the b-axis direction.
