Coordination Compounds of Tin(II) Chloride, Bromide and Isothiocyanate with Schiff Bases Derived from 2-Hydroxy-1-naphthaldehyde

Abstract

Coordinative interactions of tin(II) chloride, bromide and isothiocyanate with Schiff bases derived by the condensation of 2-hydroxy-1-naphthaldehyde with aniline having different substituents have been studied. The newly synthesised adducts of 1:2 stoichiometry (tin(II) halides and isothiocyanate: Schiff base) have been characterised by elemental analysis and IR spectral data. The compounds were examined for antibacterial and antifungal activity. The compounds have moderate antimicrobial activity. Conductance measurements indicate considerable dissociation of the compounds in solution.
