complex ( t Bu-DAC = 1,3-bis(N- tert -butyl)diamidocarbene, COD = 1,5-cyclooctadiene) reacts with titanocene(II) and zirconocene(II) sources to form heterobimetallic complexes by metallocene coordination at the remote oxalamide binding site. Structural and spectroscopic data reveal the formation of a doubly-reduced [ t Bu-DAC] 2− ligand upon metallocene complexation. The metallocene-substituted complexes
