Crystal structure and absolute configuration of the palladium(II) pinenyl complex [Pd(eta(3)-beta-C10H15)(PPh3)Cl]

An X-ray diffraction study of the palladium beta -pinenyl complex [Pd(eta ( 3)-beta -C10H15)(PPh3)Cl] was conducted. The crystals of the complex are mo noclinic: a = 10.131(3) Angstrom, b = 24.431(4) Angstrom, c = 10.766(4) Ang strom; beta = 109.31(3)degrees; V = 2514.8(9) Angstrom (3); Z = 4; space gr oup P2(1). The unit cell contains two crystallographically independent mole cules with nearly the same structures and similar geometric parameters. In both molecules, the Pd atom is bonded to the Cl atom (av. Pd-Cl, 2.289(7) A ngstrom), the P atom (av. Pd-P, 2.367(6) Angstrom). and the beta -pinenyl l igand. This ligand is coordinated with palladium through the allyl fragment in the eta (3) mode (Pd-C, 2.12(2)-2.32(2) Angstrom). The absolute configu ration of both molecules is the same: [SP-4-A-(1R,2S,3S,5R)].
