2,2′-Bis(2-indenyl) biphenyl is an organic compound with the formula [C₆H₄C₉H₇]₂. The compound is the precursor, upon deprotonation, to ansa-metallocene complexes within the area of transition metal indenyl complexes.

Metals studied with 2,2′-bis(2-indenyl) biphenyl include titanium, zirconium, and hafnium.^{[citation needed]} The ligand and its complexes have been prepared by the research group of the late Brice Bosnich at The University of Chicago.^[1] Zirconium and hafnium complexes made from this ligand were found to be active catalysts for the polymerization of the smallest alkenes – compounds with carbon-carbon double bonds—namely, ethylene and propylene.^{[citation needed]} The use of such complexes in the polymerization of alkenes has since been reported, and patented by DSM Research.^[2]^[3]
