Reinvestigation of the growth of thiourea urea zinc sulfate crystal is reported. Aqueous reaction of thiourea, urea and zinc sulfate in 1:1:1 mol ratio results in the formation of the well known [Zn(tu)3(SO4)] (1) (tu=thiourea) crystal and not the 'so called' novel semiorganic nonlinear optical thiourea urea zinc sulfate (2) crystal, as claimed by Redrothu Hanumantha Rao, S. Kalainathan, Spectroscopic
据报道对硫脲脲锌硫酸盐晶体的生长进行了重新研究。硫脲,尿素和硫酸锌以1:1:1摩尔比进行的水反应导致形成众所周知的[Zn(tu)3(SO4)](1)(tu = thiourea)晶体,而不是所谓的如Redrothu Hanumantha Rao,S.Kalainathan所述,新型半有机非线性光学硫脲脲硫酸锌(2)晶体,新型半有机非线性光学晶体-硫脲脲的光谱研究,成核,生长,光学,热和二次谐波研究硫酸锌,Spectrochim。Acta A97(2012)456-463。在这项工作中,我们证明了元素分析数据,红外光谱和NMR光谱以及X射线粉末模式对于准确表征产品的有用性。
