| Abstract: | Abstract Reaction of tri-n-butyl tin(IV) chloride with the sodium salt of Schiff bases salicylidene-2-aminopyridine (sapH), salicylidene-2-amino-4-picoline (sapicH), salicylidene-2-methyl-1-aminobenzene (o-smabH), salicylidene-4-methyl-1-aminobenzene (p-smabH), salicylidene-1- aminobenzene (sabH), salicylidene-3-nitro-1-aminobenzene (snabH)] in MeOH-C6H6 mixture in 1:1 molar ratio produced complexes of the type Bun 3Sn(sb)] (where sb = Schiff bases). All complexes obtained were characterized by elemental analysis (C, H, N, and Sn), infrared (IR), nuclear magnetic resonance (NMR; 1H, 13C, and 119Sn), and TOF-MS spectroscopic studies. These complexes were found to be monomeric, colored viscous liquids and are soluble in polar solvents (methanol, ethanol, DMSO, and DMF). On the basis of 119Sn NMR observations, a five coordination geometry around tin(IV) atom in these complexes is proposed tentatively. |
