(Received 6 March 2013; accepted 12 March 2013; online 16 March 2013)

The mol­ecular structure of the title compound, [CuCl2(C11H20N2S)2], shows the CuII atom with a distorted tetra­hedral geometry from two Cl atoms [Cu—Cl = 2.2182 (6) Å] and two thione S atoms [Cu—S = 2.3199 (6) Å]. The angles at the copper cation, which lies on a twofold rotation axis, are Cl—Cu—Cl = 142.84 (4)°, Cl—Cu—S = 94.80 (2) and 99.97 (2)°, and S—Cu—S = 132.46 (4)°. The planes of the two imidazolium rings make a dihedral angle of 76.92 (8)°.

Experimental top

To a solution of 1,3-diisopropyl-4,5-dimethylimidazoline-2-thione (0.584 mg, 2.75 mmol) in acetonitrile (40 ml) CuCl2 H2O (0.168 mg, 1.25 mmol) was added and the mixture was stirred at room temperature for 48 h. Afterwards the solvent was removed under vacuum. Blue crystals were obtained from an acetonitrile solution by diethyl ether diffusion.

Refinement top

All Hydrogen atom positions were clearly derived from difference maps, then refined at calculated positions riding on the parent atoms with C—H 0.98 - 1.00 Å and isotropic displacement parameters Uiso(H) = 1.2Ueq(C) or 1.5Ueq(CH3). All CH3 hydrogen atoms were allowed to rotate but not to tip.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
