Abstract

The structure of trans-(η¹-ally)chlorobis(triphenylphosphine)platinum(II), Pt(η¹-C₃H₅)Cl(PPH₃)₂, has been determined from three-dimensional X-ray data. The compound was isolated while attempting to grow crystals of [Pt(η³-C₃H₅)(PPH₃)₂]Cl. The complex crystallizes in the space group C⁵_2hP2₁/n with four molecules in a unit cell of dimensions a = 12.580(3), b = 23.067(7), _c = 12.316(4) Å and β = 112.30(1)°. Least-squares refinement of the 136 variables has led to a value of the conventional R index (on F) of 0.048 for the 6289 independent reflections having F²_o > 3σ(F²_o). The complex is a typical square-planar Pt(II) complex; structural parameters: PtP 2.304(2) and 2.302(2), PtCl 2.425(2), PtC(1) 2.090(4), C(1)C(2) 1.464(7), C(2)C(3) 1.311(9) Å, PtC(1)C(2) 112.6(3)°, C(1)C(2)C(3) 125.7(6)°. The angle between the plane of the allyl group and the mean coordination plane is 66°; the torsion angle PtC(1)C(2)C(3) is -119°. The structure is compared with other Pt(II) σ-complexes, and production of the complex rationalized. The isolation of the complex supports suggestions that the fluxionality of [Pt(η³-C₃H₅)(PPH₃)₂]Cl in solution involves a short-lived σ-allyl intermediate.
