摘要

Dichloro-bis(indenyl)zirconium(IV) reacts with lithium derivatives of diphosphanes Rb>2b>P-P(SiMeb>3b>)Li (R = ^tBu, Etb>2b>N, ⁱPrb>2b>N) to form complexes with terminal phosphanylphosphido ligands - [Indb>2b>Zr(Cl)-{(PSiMeb>3b>)P-PRb>2b>-魏P¹}]. These compounds are extremely sensitive towards moisture and oxygen. The solid state structures of these complexes were established by single crystal X-ray diffraction. The nitrogen bearing groups R (Etb>2b>N or ⁱPrb>2b>N) significantly lengthen the P-P distances in the related complexes and change the geometry around the phosphido phosphorus in such a way that it becomes less planar.
