Structural and Biocidal Studies of Organotin(IV) Complexes of Triazene-1-Oxides

Abstract

Five co-ordinate and six co-ordinate complexes of triorganotin(IV) and diorganotin(IV) involving variedly substituted monobasic bidentate triazene-1-oxides (TH) have been synthesised. Trigonal bipyramidal structure for five co-ordinate and trans-diorgano octahedral structure for six co-ordinate complexes have been assigned on the basis of analytical data, conductance values, molecular complexities in freezing benzene IR and Mössbauer spectral data. Antibacterial activity of triazene-1-oxides, organotin(IV) compounds R₃SnX₂ and R₃SnX and organotin(IV) complexes of triazene-1-oxides R₂SnT₂, and R₃SnT were examined using Agar-plate diffusion technique. Following order of biocidal activity has been found:

                                R₂SnX₂ < TH < R₃SnX < R₂SnT₂ < R₃SnT
