title: Dichlorobis(dibenzylamino)bis(tetrahydrofuran)zirconium(IV) toluene hemisolvate.
abstract: The title complex, [ZrCl2(C4H8O)2(C14H14N)2].0.5C7H8, 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.
