Physico-Chemical Characterization of Bioactive Mixed Ligand Complexes of Antimony with 3,5-Diarylsubstituted Pyrazolinates and O,O’-Alkylene Dithiophosphates
Antimony(III) complexes of 3(2’-hydroxyphenyl)-5-(4’-substituted phenyl) pyrazolinates and O,O’-alkylene dithiophosphate of the type [Sb(C15H12N2OX)(GO2PS2)]Cl and [Sb(C15H12N2OX)2(GO2PS2)] (where GO2PS2 – deprotonated O,O’-alkylene dithiophosphate; C15H12N2OX – deprotonated 3(2'-hydroxyphenyl)-5-(4’-subsitutedphenyl) pyrazolinates; X = –H,–CH3, –OCH3 and –Cl; G = –C(CH3)2CH2CH(CH3)–) have been synthesized and characterized by elemental analysis (C, H, N, Cl and Sb), molecular weight study by FAB mass, electronic spectral studies, far and mid IR, multinuclear NMR (1H,13C and 31P).
