COMPARATIVE STUDY OF THIOUREA METAL COMPLEXES CRYSTALS

摘要

The thiourea is an interesting inorganic matrix modifier. Recently, researchers are focusing on growing metal complexes of thiourea crystals. Some of the examples are bis thiourea zinc chloride (BTZC) , tetrakis thiourea potassium iodide (TTPI) , tetra thiourea potassium iodide (TTPI) , tetra thiourea cobalt chloride (TTCoC) , bis thiourea cadmium chloride (BTCC) etc., Anand et al, Gopinath et al and Mariappan et al have reported the growth and characterization of metal complexes of urea thiourea. This paper aims to compare the optical, mechanical and thermal properties of these crystals.
