| Abstract: | Bimetallic thiocyanate complexes crystal materials belonging to ABTC structure type: ZnCd(SCN)4 and AHg(SCN)4 (A = Zn, Cd, Mn ) which are potentially useful in second harmonic generation (SHG) have been prepared. Their structural, optical and physicochemical properties are characterized by infrared spectroscopy, X‐ray powder diffraction, vis/UV/NIR spectroscopy, SHG measurements and thermal analysis. The states of crystal growth solutions are discussed in this article. The crystals belong to tetragonal system with the space group I‐4 and exhibit SHG efficiencies over one order of magnitude higher than that of Urea. Their transparency cutoffs lie in the UV region, and they possess good physicochemical stabilities. |
