Abstract

Coordination compounds of biurates with thiosemicarbazide [Mn(HL)2](Urat)2(H2O)2, [Co(HL)3](Urat)3(H2O)3, [Ni(HL)2](Urat)2(H2O)2, and [Ni(HL)2](Urat)2(H2O)4, where HL is thiosemicarbazide, and Urat is the anion of uric acid dissociated by the first step, were synthesized. The physicochemical properties and structures of the compounds were studied by IR and diffuse reflection spectroscopies, magnetochemistry, and DTA.
