Crystal structure of the monoclinic phase (phase IV) of bis(tetramethylammonium) tetrachloridocuprate(II)

The crystal structure of the low-temperature monoclinic phase of the title compound, [(CH 3 ) 4 N] 2 [CuCl 4 ], was determined at 120 K. The structure of the room-temperature phase has been determined in the orthorhombic space group Pmcm [Morosin & Lingafelter (1961). J. Phys. Chem. 50–51; Clay et al. (1975). Acta Cryst. B 31 289–290]. 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.
