%X Reactions of HC5Me(CO2Me)4 or TI[C5Me(CO2Me)4] with appropriate precursors have afforded the compounds ML2{C5Me(CO2Me)4}2 (M = Mn , L = H2O; M = Cu, L = MeOH ), Rh (&#331;4C8H12 )}&#331;5 -C5Me(CO2Me)4}, Rh {C5Me(CO2Me)4]2,RU(&#331;-C5H5){&#951;5(C5Me(CO2Me)4}, Cu{C5Me(CO2Me)4}-(PPh3)2 and M{C5Me(COP2Me)4}(PPh3)(M=Ag or Au). There appear to be no significant differences between these compounds and analogous species derived from HC5(CO2Me)5, except for the expected spectroscopic changes. The molecular structure of Au{C2Me(CO2Me)4}(PPh3) closely resembles that of Au{C5(CO2- Me)5}(PPh3); the methyl group is on the ring carbon adjacent to that which most closely interacts with the Au(PPh3) group. Crystals are monoclinic, space group P21/c, with a 10.313(2), b 10-388(3), c 28.637(11)Å, &#946; 97.01(3)º, Z 4; 3571 data with I> 3&#963;) were refined to R 0.037, R&#8242;0.033.
