Abstract

The crystal and molecular structure of trans-bromo(trans-styryl)bis(triphenylphosphine)platinum(II), PtBr(HC=CHC₆H₅)(P(C₆H₅)₃)₂, prepared by the oxidative addition of trans-β-bromostyrene to Pt(P(C₆H₅)₃)₃, has been determined from three-dimensional X-ray data collected by counter techniques. Crystal data are the following: monoclinic; space group C_2h ⁵-P2₁/c; a = 14.857 (3), b = 16.339 (5), c = 16.980 (4) Å; β = 118.30 (1)° (temperature 22°); Z = 4; d_obsd = 1.64 (2), d_calcd = 1.650 g cm^-3. The structure was refined using 3123 independent reflections for which F_o ² > 3σ(F_o ²) and the refinement converged to a conventional R index of 0.031. The coordination around the platinum atom is tetragonal planar and the σ-styryl group has a trans geometry indicative of stereospecific oxidative addition. The addition of cis-β-bromostyrene to the platinum(0) complex is reported, and the mechanistic and stereochemical aspects of the addition of other vinyl halides are discussed.
