Synthesis and Characterization of Some New Monophenylbismuth(III) Derivatives of N, O, and S Containing Schiff Bases

Abstract

Some new monophenylbismuth(III) complexes of the type PhBi[SC₆H₄N:C(R)CH₂C(O)R′]₂ [where R = CH₃, R′ = CH₃ (1); R = CH₃, R′ = C₆H₅ (2); R = CF₃, R′ = $$ (3); R = CF₃, R′ = C₆H₅ (4)] have been synthesized by the reactions of Ph₃Bi with corresponding benzothiazoline ligands, H$$(R)CH₂C(O)R′ in 1:2 molar ratios in benzene solution. All these derivatives have been characterized by the elemental analyses, molecular weight measurements, and their probable structure has been proposed on the basis of IR and NMR (¹H and ¹³C) spectral studies.
