Abstract:

Several chiral clusters RuCoMo(μ-3 S)(CO) 8C 5H 4C(O)R were synthesized by the thermal reaction of the precursor (μ-3 S)RuCo2(CO) 9 with functionally substituted cyclopentadienyl tricarbonyl metal complex anions [M(CO) 3(η5-C5H4)C(O)R] -(R=H,CH3,C6H5,C 6H 4C(O)OCH 3;M=Mo,W)in THF. All of these clusters were characterized by C/H elemental analysis, IR and 1H NMR. Crystal structure of the cluster (μ-3 S)RuCoMo(CO)8CpCOC6H5 has also been solved by single crystal X ray diffraction.
