| Abstract: | Treatment of Ru3(CO)12 with salicylaldimines 2-HOC6H4-CH?=N–C6H4-4-R] R?=?Me; Cl; Br; OMe; CF3] in refluxing toluene gave three novel binuclear ruthenium carbonyl complexes {µ-?2-2-OC6H4-CH=N-C6H4-4-R)]µ-?2-2-CH2-OC6H4]µ-?-NH-C6H4-4-R]}Ru2(CO)4 R?=?Me (1), Cl (2), Br (3)] and three mononuclear carbonyl complexes 2-OC6H4-CH=N-C6H4-4-R]2-OC6H4-CH2NH-C6H4-4-R]Ru(CO)2 R?=?Me (4), OMe (5), CF3 (6)], respectively. The structures of 1–6 were fully characterized using IR and NMR spectroscopy, elemental analysis and single-crystal X-ray diffraction. These results suggest that the substituent group on the phenyl of salicylaldimine has a significant effect on the structure of the Ru complex. |
