Abstract
Bimetallic thiocyanate complexes crystal materials belonging to ABTC struct ure type: ZnCd(SCN)(4) and AHg(SCN)(4) (A = Zn, Cd, Mn) which are potential ly useful in second harmonic generation (SHG) have been prepared. Their str uctural, optical and physicochemical properties are characterized by infrar ed spectroscopy, X-ray powder diffraction, vis/UV/NIR spectroscopy, SHG mea surements and thermal analysis. The states of crystal growth solutions are discussed in this article. The crystals belong to tetragonal system with th e space group 14 and exhibit SHG efficiencies over one order of magnitude h igher than that of Urea. Their transparency cutoffs lie in the UV region, a nd they possess good physicochemical stabilities.
