Novel dinuclear dihydride complexes of ruthenium containing bridging carboxylate ligands
Abstract
The dinuclear tetrahydride-bridged ruthenium complex (η5-C5Me5)Ru(µ-H)4Ru(η5-C5Me5) reacts with carboxylic acid RCO2H (R = H, Me, CF3, C6H5, adamantyl) in tetrahydrofuran (thf) to afford the novel dinuclear dihydride complexes (η5-C5Me5)Ru(µ-H)2(µ-RCO2)2Ru(η5-C5Me5) containing two bridging carboxylate ligands, the reactivities and the X-ray crystal structure of which are also reported.
