The preparation of Hg(NH3)2Cl2 doped with a small amount of Cu2+ is reported. The EPR and ligand field reflectance spectra indicate the presence of “CuCl4(NH3)2” polyhedra with a compressed tetragonal geometry and confirm, that the centres in Cu2+ doped NH4Cl possess the same geometry - as postulated earlier. The Cu2+ centres in Hg(NH3)2Cl2 are less compressed than those in NH4Cl, however, as could be deduced from the copper(II) hyperfine values, which are strongly influenced by the quite different admixture of the metal 4s orbital into the Alg (dz2) ground state in the two cases, and from the comparable energies of the d - d transitions.
