%X The reaction between Ru3(CO)12 and Ni{&#951;1,&#951;2-C5H5C2(CO2Me)2}Cp afforded orange Ru2{&#956;-&#951;1,O:&#951;2-C(CO2Me)=CHC(O) Ome }(CO)4Cp(43%) as the only isolable complex. An X-ray structure determination showed that a C(CO2Me)=CHC(O) OMe  ligand bridges an Ru-Ru bond [2.7744(9) &#506;] via a &#956;-&#951;1:&#951;2-vinyl interaction and by coordination of one of the ester CO groups [ Ru -O 2.148(2) &#506;]. One ruthenium atom bears three terminal CO ligands and the other ruthenium atom has one CO ligand and an &#951;5-C5H5 group. In the reaction, transfer of Cp and the vinyl group (from the bicyclo [2.2.1]hepta-2,5-dienyl ligand originally present) from nickel to ruthenium has occurred.
