Crystal structure of bis[μ-N-(η²-prop-2-en-1-yl)piperidine-1-carbothioamide-κ² S:S]bis[(thiocyanato-κN)copper(I)]

Abstract

The title crystalline compound, [Cu2(NCS)2(C9H16N2)2], was obtained from the reaction of copper(I) thiocyanate (CuSCN) with (N-prop-2-en-1-yl)piperidine-1-carbothioamide as a chelating and bridging thiourea ligand in chlorobenzene. The Cu2S2 core of the dimeric molecule is situated on a crystallographic inversion centre. The copper atom is coordinated by a thiocyanate nitrogen atom, each sulfur atom of the two thiourea ligands, and the C=C double bond of the ligand in a distorted tetrahedral geometry. The dimers are linked by N—H...S hydrogen bonds, forming a network extending in two dimensions parallel to (100).
