[(CH3)4N]2Zn0.5Cu0.5Cl4 shows an orthorhombic system at ambient temperature with P2(1)nb space group. At room temperature, the crystal consists of three sublattices constituted by MCl4 (M=Cu and Zn) and two tetramethylammoniums N1(CH3)4 and N2(CH3)4, which give rise to a total of 372 vibrational modes that transform according to the four irreductible representations of the C2v point group in the following way: Gamma(vib)=93(A1+A2+B1+B2). The infrared and Raman spectra of polycrystalline samples have been investigated at room temperature. The assignment of the observed bands is discussed.
