Abstract: The title compound, [Zr(Cl)₂(C₂₁H₂₅N₂)(C₅H₅)], [bis(2,6-dimethylphenyl)nacnac](cp)ZrCl₂, where nacnac is the pentane-2,4-diiminate ligand and cp is cyclopentadiene, has pseudo-tetrahedral coordination geometry about the Zr center. The coordination mode of the nacnac ligand is intermediate between ²- and ⁵-coordination, with both N atoms and two C atoms clearly coordinated to the Zr center. The coordination is best described as an in-plane ¹-imine and an ³-enaminato coordination of the nacnac ligand.
