Abstract

The title compound, (C₆H₈N)₂[CuCl₄], crystallizes in the monoclinic space group I2/c. The coordination around the copper atom is a distorted tetra-hedron. The 2-methyl-pyridinium ion (C₆H₈N⁺) inter-acts with the tetra-chloro-cuprate anion through N-H⋯Cl and C-H(phen-yl)⋯Cl contacts, forming a hydrogen-bonded layer-like structure. The supra-molecular structure is further stabilized by C-H(meth-yl)⋯Cl inter-actions between the layers.

Keywords: 2-picoline complex; crystal structure; hydrogen bonding; inorganic supramolecular chemistry.
