Stereochemical Studies on Cobalt (II) and Nickel (II) Complex of Some Semi Carbazones

Abstract

Cobalt (II) and nickel (II) complexes of acetone semicarbazone and ethylmethylketone semicarbazone have been synthesised and characterised by elemental analysis, magnetic susceptibility measurements, IR and electronic spectral studies. All cobalt(II) complexes are octahedral. Nickel(II) complexes, on the other hand, show stereochemical variations depending upon the aims involved; thiocyanato and nitrato complexes are six-coordinate octahedral and chloro and sulphato complexes are five coordinate trigonal bipyramidal
