A new nonlinear optical complex crystal tetrakis (thiourea) mercury (II) tetrakis (thiocyanato-N) zinc (II) was synthesized and its structure was determined. It belongs to the tetragonal system, Ispace group. The crystal structure consists of discrete [Zn(SCN)4]2- anions and [Hg(NH2CSNH2)4]2+ cations with slightly distorted coordination tetrahedra ZnN4 and HgS4. The second harmonic generation (SHG) of the crystal was found to be superior to that of urea.
