Synthesis and spectral studies of binuclear ruthenium(II) carbonyl complexes containing bis(β-diketone) and their applications

A series of new binuclear ruthenium(II) complexes of the type {[RuX(CO)(AsPh3)(2)](2)L} (X = H or Cl; L = bis-beta-diketone) have been synthesised by reacting [RuHX(CO)(AsPh3)(3)] (X = H or Cl) with various bis(beta-diketones) of the general formula [(RCO)(R'CO)CH-CH(R)-CH(COR)(COR')] (R = CH3 or C6H5; R' = CH3 or C6H5; R = H, C6H5, 4-(CH3)C6H4, 4-(OCH3)C6H4 or 4-N(CH3)(2)C6H4) in 2:1 molar ratio in benzene. An octahedral structure has been tentatively proposed for all the new ligand bridged binuclear complexes. The new complexes have been subjected to the antibacterial and catalytic activity studies.
