Crystal structure of -poly[[[di-chlorido-copper(II)]-{μ--butyl -methyl--[4-(6-{[4-(pyridin-2-yl-κ)-1-1,2,3-triazol-1-yl-κ]meth-yl}-1,3-benzo-thia-zol-2-yl)phen-yl]carbamato}] aceto-nitrile monosolvate].

In the title coordination polymer, {[CuCl(CHNOS)]·CHCN} , the copper(II) ion is fivefold coordinated, with an almost perfect square-pyramidal coordination sphere. In the equatorial plane, it is ligated to a pyridine N atom and an N atom of the triazole unit and to two Cl ions, while the apical position is occupied by the carbonyl O atom of the -butyl carbamate group. In the crystal, the polymer chains propagate in the [11-1] direction, with the aceto-nitrile solvent mol-ecules linked to the chain by C-H⋯N hydrogen bonds.
