Abstract
A series of organosilicon(IV) and organotin(IV) complexes having the formulae R2MCl(L1), R2MCl(L2), R2MCl(L3), R2MCl(L4), R2M(L1)2, R2M(L2)2, R2M(L3)2, and R2M(L4)2, where M = Si and Sn, and R = CH3, were synthesized with Schiff bases 5-mercapto-4-(pyridine-2-carboxalideneamino)-s-triazole (HL1), 4-(furfuralideneamino)-5mercapto-s-triazole (HL2), 4-(2-chlorobenzylideneamino)-5-mercapto-s-triazole (HL3), and 4-(4-flourobenzylideneamino)-5-mercapto-s-triazole (HL4). These complexes were characterized by elemental analysis, molar conductance, and spectroscopic studies, including UV, IR, 1H, 13C, 29Si, and 119Sn NMR spectroscopy. On the basis of these studies, the resulting complexes are proposed to have trigonal bipyramidal and octahedral geometries.
