Bis(2,2′-bi-1H-imidazole-κ2N3,N3′)(thiocyanato-κN)copper(II) chloride

Abstract

In the title salt, [Cu(NCS)(C6H6N4)2]Cl, the CuII atom adopts a five-coordinated square-pyramidal geometry consisting of an N atom from a thiocyanate anion and four N atoms from two chealting biimidazole ligands. The thiocyanate ligand occupies the axial position and is, like the CuII centre, located on a mirror plane. The cation and anion are linked into a linear chain by N—H...S and N—H...Cl hydrogen bonds.
