The ansa-zirconocene [bis-(η5-cyclo-pentadienyl) phenylphosphine]-dichloridozirconium(IV)

In the title compound, [Zr(C16H13P)Cl2], the geometry at the metal atom is distorted tetrahedral; the Cl-Zr-Cl angle is 101.490 (16)° and the cyclopentadienyl (Cp) centroids subtend an angle of 122.63 (3)° 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)° reflects the pincer effect of the two Cp rings. Three C-H...Cl, one C-H...P, one C-H...π and one Cl...P inter-action link the mol-ecules to form thick layers parallel to the bc plane.

Preparation of phenylplatinum-zirconium complexes with Ph2PC5H4 or PhP(C5H4)2 bridging ligands and their reactions with carbon monoxide

Reaction of [PtPh2(cod)] or [PtClPh(cod)] with (Ph2PC5H4)2ZrCl2 yields the Ph2PC5H4-bridged species [PtXPh(Ph2PC5H4)2ZrCl2] (X = Ph, Cl). Treatment of [PtPh2(cod)] or [PtClPh(cod)] with 2 equiv of PhP(C5H4)2ZrCl2, prepared by reaction of [ZrCl4(THF)2] with (TlC5H4)2PPh, yields cis- [PtPh2{PhP-(C6H4)2ZrCl 2}2] or trans-[PtClPh{PhP(C5H4)2ZrCl2} 2]. Each of the mixed-metal complexes has been isolated as an air-sensitive solid and characterized by elemental analysis and NMR spectroscopy. [PtPh2-(Ph2PC5H4) 2ZrCl2] does not react with carbon monoxide, and cis-[PtPh2{PhP(C5H4)2ZrCl 2}2] undergoes a slow displacement of phosphine by CO, whereas the two chlorophenylplatinum complexes undergo smooth carbonylation to the corresponding benzoylplatinum species.
