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.
