Abstract :A series of organosiliconinsert ignore into journalissuearticles values(IV); and organotininsert ignore into journalissuearticles values(IV); complexes having the formulae R2MClinsert ignore into journalissuearticles values(L1);, R2MClinsert ignore into journalissuearticles values(L2);, R2MClinsert ignore into journalissuearticles values(L3);, R2MClinsert ignore into journalissuearticles values(L4);, R2Minsert ignore into journalissuearticles values(L1);2, R2Minsert ignore into journalissuearticles values(L2);2, R2Minsert ignore into journalissuearticles values(L3);2, and R2Minsert ignore into journalissuearticles values(L4);2, where M = Si and Sn, and R = CH3, were synthesized with Schiff bases 5-mercapto-4-insert ignore into journalissuearticles values(pyridine-2-carboxalideneamino);-s-triazole insert ignore into journalissuearticles values(HL1);, 4-insert ignore into journalissuearticles values(furfuralideneamino);-5mercapto-s-triazole insert ignore into journalissuearticles values(HL2);, 4-insert ignore into journalissuearticles values(2-chlorobenzylideneamino);-5-mercapto-s-triazole insert ignore into journalissuearticles values(HL3);, and 4-insert ignore into journalissuearticles values(4-flourobenzylideneamino);-5-mercapto-s-triazole insert ignore into journalissuearticles values(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.
