Ligational,thermal, corrosion inhibition and antimicrobial properties of salicylidinebenzenesulphonylhydrazone

Summary Complexes of Cu^II, Co^II, Ni^II, Cd^II, Zn^II and Hg^II with salicylidinebenzenesulphonylhydrazone (HSBS) have been prepared and characterized by elemental analyses, molar conductivities, magnetic moments, spectral (visible, i.r., n.m.r.) and thermal (d.t.a., t.g., d.t.g.) measurements. The magnetic and spectral studies confirm that the Ni^II complex is square, whereas the Co^II complex is tetrahedral. The molar conductivities for the complexes lie in the non-electrolyte range. The corrosion inhibition of aluminium using HSBS was studied by chemical and electrochemical methods. Also, the antimicrobial activities of HSBS and its complexes have been investigated.
