Phenylmercury derivative (phHgSA) of Schiff base SAH derived from salicylaldehyde and aniline have been prepared. Reaction of this derivative with M(NCS)₂, where M - Co^II, Ni^II, Cu^ll and Zn^II, gave complexes of general formulae (phHgSA)₂M(NCS)_2. These complexes on further reaction with pyridine or bipyridine (L) furnished adducts of general formula (phHgSA)₂ M(NCS)₂\(Lx\), where x -1 or 2. All the complexes have been characterised by elemental analysis, molecular weight, molar conductance, infrared and electronic spectral data. On the basis of these studies, probable structure of the complexes and quantitative softness parameters have been evaluated.
