Synthesis and Spectroscopic Studies of Mixed N-(Salicylidene)-O-Mercaptoaniline Dialkyldithiophosphato Derivatives of Antimony(III)

Abstract

Mixed N-(salicylidene)-o-mercaptoaniline dialkyldithiophasphato derivatives of antimony(III) were synthesized by the substitution reactions of chlorobis [N-(salicylidene)-o-mercaptoaniline] antimony(III), Sb[SC6H4N=C(H)C6H4OH]2Cl; dichloro [N-(salicylidene)-o-mercaptoaniline] antimony(III), Sb[SC6H4N=C(H)C6H4OH]Cl2 and monochloro [N-(salicylidene)-o-mercaptoaniline]antimony(III), Sb[SC6H4N=C(H)C6H4O]Cl with the ammonium salt of dialkyldithiophosphates in 1:1, 1:2 and 1:1 molar ratios, respectively, in benzene. These yellow or orange crystalline complexes have been characterized by elemental analysis, melting points, molecular weight measurements and spectroscopic (IR, 1H, 13C and 31P NMR) studies.
