ruthenium carboxylato carbonyl dinuclear complex prepn crystal mol structure
Abstract
The thermal reaction of Ru3(CO)12 with ethacrynic acid, 4-[bis(2-chlorethyl)amino]benzenebutanoic acid (chlorambucil), or 4-phenylbutyric acid in refluxing solvents, followed by addn. of 2-electron donor ligands (L), gives the diruthenium complexes Ru2(CO)4(O2CR)2L2 (1: R = CH2O-C6H2Cl2-COC(CH2)C2H5, L = py; 2: R = CH2O-C6H2Cl2-COC(CH2)C2H5, L = PPh3; 3: R = C3H6-C6H4-N(C2H4-Cl)2, L = py; 4: R = C3H6-C6H4-N(C2H4-Cl)2, L = PPh3; 5: R = C3H6-C6H5, L = py; 6: R = C3H6-C6H5, L = PPh3). The single-crystal structure analyses of 2, 3, 5, and 6 reveal a dinuclear Ru2(CO)4 sawhorse structure, the diruthenium backbone being bridged by the carboxylato ligands, while the 2 L ligands occupy the axial positions of the diruthenium unit.
