Dimeric and monomeric six-coordinate tin(IV) complexes: synthesis and spectral (IR, NMR (1H, 13C, 119Sn), TOF-MS, and ESI-MS) studies
摘要:
Six-coordinate dimeric tin(IV) complexes, [(-Cl)(2)Sn-2((2)-sb)(2)Cl-4] {where sb=salicylidene-2-methyl-1-aminobenzene (o-smabH) (1), salicylidene-4-methyl-1-aminobenzene (p-smabH) (2), and salicylidene-2-aminopyridine (sapH) (3)}, have been synthesized by interactions of tin(IV) chloride with the appropriate sodium salt of Schiff bases in 1:1M ratio in isopropanol-benzene. These complexes have been characterized by elemental (C, H, N, and Sn) and spectral [IR, NMR (H-1, C-13, Sn-119), TOF-MS, and ESI-MS] studies. Complexes 1-3 on treatment with an excess of THF afford mononuclear six-coordinate tin(IV) complexes, [(sb)SnCl3THF], 4-6. The biological activities (e.g. antimicrobial action) of the synthesized Schiff bases and 1-3 were assessed by in vitro testing on the growth of various strains of bacteria and fungi.
