Cp glue: A chiral four-coordinate organolanthanoid complex, which has an unsupported metal–metal bond, reacts to give a lanthanoid–transition-metal cluster with two-electron multicenter metal–metal bonds (see structure). The reaction proceeds through C[BOND]H bond activation by the polar metal–metal bonds and affords a 1,2-dimetallation of one Cp ligand of the metallocene moiety.
