摘要：

The monomeric molecule of the title compound, [NbCl2-(C9H13)2], is best described as a paramagnetic pseudo-tetrahedral complex of niobium(IV). The two tert-butylcyclopentadienyl ligands are asymmetrically bound to the Nb atom [Nb-C bond-length range 2.394 (6)-2.470 (6) angstrom]. The asymmetry is accounted for in terms of the steric demand of the (t)Bu groups and Cl ligands. Pseudo-tetrahedral geometry is completed by two Cl ligands [Nb-Cl 2.477 (2) and 2.483 (2) angstrom, Cl-Nb-Cl 84.15 (6)-degrees].
