N2 - The title complex, [ZrCl2(C4H8O)(2)(C14H14N)(2)].0.5C(7)H(8), was prepared in an unusual manner by utilizing [Mg{N(CH2Ph)(2)}(2)] as a ligand transfer reagent. The Zr atom lies in a distorted octahedral environment where steric repulsion from the large dibenzylamino ligands leads to a widening of the N-Zr-N angle [99.95 (9)degrees] and corresponding compression of other angles [Cl-Zr-Cl 160.95 (3)degrees and O-Zr-O 78.22 (7)degrees]. This distortion is compared with those found in the previously determined structures of the dimethylamino and diethylamino analogues.
