A modified ap ligand, 2-(3,5-dimethoxyanilino)pyridine (HDiMeOap) and its diruthenium compounds Ru2(DiMeOap)4Cl (1), Ru2(DiMeOap)4(C CC CSiMe3) (2) and Ru2(DiMeOap)4(C CC CSiMe3)2 (3) were prepared and characterized. New compounds Ru2(MeOap)4(C CC CSiMe3)x (x = 1, 4; 2, 5; MeOap is 2-(3-methoxyanilino)pyridinate) were prepared from the previously reported Ru2(MeOap)4Cl. In addition, two related diruthenium compounds containing ferrocenyl acetylide ligand, Ru2(MeOap)4(C CFc) (6) and Ru2(ap)4(C CC CFc) (7), were synthesized. Molecular structures of compounds 1, 2, 6 and 7 were established using single crystal X-ray diffraction study. |
