Abstract :
The crystal structure of the low-temperature monoclinic phase of the title compound, [(CH3)4N]2[CuCl4], was determined at 120 K. The structure of the room-temperature phase has been determined in the orthorhombic space group Pmcm [Morosin & Lingafelter (1961[Morosin, B. & Lingafelter, E. C. (1961). J. Phys. Chem. 65, 50-51.]). J. Phys. Chem. 50–51; Clay et al. (1975[Clay, R., Murray-Rust, J. & Murray-Rust, P. (1975). Acta Cryst. B31, 289-290.]). Acta Cryst. B31 289–290]. The asymmetric unit consists of one discrete tetrachloridocuprate anion with a distorted tetrahedral geometry and two tetramethylammonium cations. In the crystal, the cations and the anions are linked via weak C—H⋯Cl hydrogen bonds.
