Crystal structure of bis(N,N,N′,N′-tetramethylguanidinium) tetrachloridocuprate(II)

Abstract

In the structure of the title salt, (C5H14N3)2[CuCl4], the CuIIatom in the anion lies on a twofold rotation axis. The tetrachloridocuprate(II) anion adopts a flattened tetrahedral coordination environment and interacts electrostatically with the tetramethylguanidinium cation. The crystal packing is additionally consolidated through N—H...Cl and C—H...Cl hydrogen bonds, resulting in a three-dimensional network structure.
