| Abstract: | Three distinct cobalt complexes of 2-hydroxy-4-benzamidothiosemicarbazide, Co(C8H9N4O2S) (H2O)3] Cl (I), Co(C3H9N4O2S) (OH) (H2 O)2] (II) and Na Co(C8H9N4 O2 S) (OH)3] H2 O (III) have been prepared at pH 3.0, 9.0 and 12.5, respectively. Magnetic measurements show subnormal values of the magnetic moment for high-spin octahedral cobaltous complexes. A possible correlation has been sought in nephelauxetic ratio, calculated from electronic spectral data. The values of 10 Dq, L.F.S.E. and Racah's interelectronic repulsion parameters have also been evaluated. The complex (III) is diamagnetic in nature. |
