    • 2-, tmbp = 4,4′,5,5′-tetramethyl- 2,2′-bisphosphinine. However, X-ray structural data for the Zr analog indicates that significantly reduced tmbp ligands are present, which strongly suggests that the tmbp ligand in the hafnate also has redox-noninnocent character. See: P. Rosa, N. Mezailles, L. Ricard, F. Mathey, P. LeFloch, Angew. Chem. 2000, 112, 1893;
