Bis(2-methylpyridinium) tetrachloridocuprate(II): synthesis, structure and Hirshfeld surface analysis

Abstract

The title compound, (C6H8N)2[CuCl4], crystallizes in the monoclinic space group I2/c. The coordination around the copper atom is a distorted tetrahedron. The 2-methylpyridinium ion (C6H8N+) interacts with the tetrachlorocuprate anion through N—H...Cl and C—H(phenyl)...Cl contacts, forming a hydrogen-bonded layer-like structure. The supramolecular structure is further stabilized by C—H(methyl)...Cl interactions between the layers.
