| Abstract: | Reactions of γ-aminopropyltriethoxysilane and 4-(diethylamino)salicylaldehyde in ethanol afforded a Schiff base L1H, which reacted with Ru(CO)2Cl2]n in the presence of Et3N in THF giving a ruthenium(III) carbonyl complex RuCl(CO)2(η1-O-L1)(η2-O,N-L1) (1). Treatment of γ-aminopropyltriethoxysilane with 4-pyridinecarboxaldehyde gave the Schiff base L2. Interactions of L2, γ-aminopropyltriethoxysilane, and Ru(NO)Cl3?H2O in THF led to the formation of a ruthenium(II) nitrosyl complex RuCl3(NO)(L2)H2N(CH2)3Si(OEt)3] (2) with linear N≡O ligand. Complexes 1 and 2 were characterized by microanalyses and IR and MS spectroscopies and confirmed by single-crystal X-ray diffraction. |
