Abstract:
The crystal structure of oxodichloropentane-2,4-dionatotriphenylphosphinerhenium(V) has been studied by single crystal X-ray methods. The crystals are triclinic with lattice parameters a = 11.023(8) Å, b = 13.523(8) Å, c = 9.360(7) Å, α = 90.2(1)°, β = 114.1(1)°, γ = 67.7(2)°. The space group is [Formula: see text] and there are two formula weights per unit cell. A total of 2891 reflections, of which 2447 were observed, were examined, and the structure was refined by full matrix least squares to an R 2 value of 0.0782. The ligands are arranged around the rhenium atom such that the nearest six atoms are at the corners of a very distorted octahedron. Most of this distortion appears to be caused by nonbonding repulsive interactions. The short oxo–phosphine distance, 2.85(1) Å, suggests the possibility of a weak bonding interaction. Observed bond distances (Re—Cl, 2.35 Å av; Re—O(oxo), 1.69(1) Å; Re—O(diketone), 1.99(1), 2.10(1) Å; Re—P, 2.431(4) Å) are close to those observed previously in similar compounds.
