Reaction of SbCl3 with sodium salt of vanillinidene-2-methylaminobenzene (vmabH) and salicylidene-3- nitroaminobenzene (snabH) in 1: 1 and 1: 2 molar ratios afforded complexes of the type [Sb(eta(2)-sb)(n) Cl3-n](1-4) [where sb = vanillinidene-2-methyl-1-aminobenzene (vmabH) (1, 2) and salicylidene-3-nitroaminobenzene (snabH) (3, 4)]. Bismuth complexes of type [Bi(PBT)(n) Cl3-n] (5, 6) have been synthesized similarly by the reaction of BiCl3 with sodium salt of 2-(o-hydroxyphenyl)-benzothiazole (HPBT) in different molar ratios (where n = 1-2). These newly synthesized complexes of antimony and bismuth have been characterized by elemental (C, H, N, S, Sb, and Bi) analysis and spectroscopic IR, H-1 NMR, and C-13 NMR techniques. The molecular composition of three selective complexes has been confirmed by mass spectrometric studies.
