IR,PMR and Mössbauer studies on the complexes of triphenyltin chloride and triphenyltin isothiocyanate with a series of N-alkylsalicylideneimines

Eleven new complexes of the type Ph₃SnX: o-HOC₆H₄CHNR (X = Cl, NCS; R = CH₃, t-Bu, PhCH₂, n-C₆H₁₃, c-C₆H₁₁, HOCH₂CH₂) have been synthesized by the reactions of triphenyltin chloride or isothiocyanate with the N-alkylsalicylideneimines. The complexes are non-electrolytes in nitrobenzene. IR, PMR and Mössbauer spectroscopic studies indicate that the ligands are behaving as monodentates via the phenolic oxygen atoms, and that the complexes all have trigonal bipyramidal geometry with the phenyl groups occupying the equatorial positions.
