| Abstract | ||
| Measurements of stability constant of complexes formed by interaction of potassium 5-mercapto-1,3,4-oxadiazol-2-ylcarbamo dithioate (K+TC-) with (Ag+, Ca+2, Mn+2 , Co+2, Ni+2, Zn+2, Cd+2, and Pb+2 Cr+3, Fe+3, La+3 ,) ions, have been performed. The bidentate ligand (K+ TCS-) has a hardness parameter (α) of (0.350) and a softness (ß ) parameter of (0.05). Bonding in these complexes occur most probably through sulfur atom of carbonate group and ione pair electrons of the isomethine nitrogen atom for oxadiazole ring. | ||
