Abstract: The title compound, [Zr(Cl)₂(C₂₁H₂₅N₂)(C₉H₇)]·0.5C₇H₈, [bis(2,6-dimethylphenyl)nacnac](indenyl)ZrCl₂, where nacnac is the pentane-2,4-diiminate ligand, 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 ³-enaminato coordination of the nacnac ligand. A toluene solvent molecule is present and is disordered about a twofold crystallographic axis.
