heterobimetallic iron(II)–chromium(>0>) complexes [(OC)2CpFe(µ-η1∶η7-C7H6)Cr(CO)3]+ and [(OC)2CpFe(µ-η1∶η7-C2C7H6)Cr(CO)3]+ containing the bridging carbene ligand cycloheptatrienylidene C7H6 and the cumulogous allenylidene ligand (cycloheptatrienylidene)ethenylidene C2C7H6 have been prepared and their properties studied. The former has been prepared by hydride abstraction from the heterobimetallic µ-η1∶η6-cyclohepta-1
