molar conductance measurements, elemental analyses, UV–Vis, IR, 1H, 13C, 29Si NMR, and mass spectroscopy. On the basis of all these studies, penta-coordinated environment around central silicon atom in 1:1 molar ratio was proposed. The ligands and their organosilicon complexes were tested in vitro for antibacterial activity against Gram-positive bacteria viz. Staphylococcus aureus, Bacillus subtilis as
AbstractSome new di and tri-organosilicon complexes of type R2Si(L1)Cl, R3Si(L1), and R2Si(L2)/R2Si(L3) (R = Me, Et, Bu, and Ph; L1 = 4-hydroxy-6-methyl-3-[1-(quinolin-8-ylimino)ethyl]pyran-2-one, L2 = 3-[1-(2-aminophenylimino)ethyl]-4-hydroxy-6-methylpyran-2-one, and L3 = 3-[1-(2-amino-4-chlorophenylimino)ethyl]-4-hydroxy-6-methylpyran-2-one) were synthesized from Schiff base ligands derived from
