Abstract:
In the title compound, [Zr(C(16)H(13)P)Cl(2)], the geometry at the metal atom is distorted tetrahedral; the Cl-Zr-Cl angle is 101.490 (16) degrees and the cyclopentadienyl (Cp) centroids subtend an angle of 122.63 (3) degrees at the Zr atom. The P atom lies 0.474 (3) and 0.496 (3) A out of the planes of the Cp rings. The C-P-C angle of 91.42 (7) degrees reflects the pincer effect of the two Cp rings. Three C-H...Cl, one C-H...P, one C-H...pi and one Cl...P interaction link the molecules to form thick layers parallel to the bc plane.
