摘　　要：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. 1 (4) over bar space 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.A new nonlinear optical complex crystal tetrakis (thiourea) mercury (II) tetrakis (thiocyanato-N) zinc (II) was synthesized and its structure was determined.
