Crystal structure of [WI2(CO)(3){P(OMe)(3)}(2)]

[WI2(CO)(3){P(OMe)(3)}(2)] crystallizes in the orthorhombic space group Pca 2(1), with a = 26.924(5), b = 10.726(2), c = 14.136(3) Angstrom, and Z = 8. There are two molecules in the asymmetric unit, the metal atoms in each ca se being seven-coordinate with a capped fac-(CO)(3) octahedral geometry. Th e molecular dimensions in the two molecules are nearly identical. The W-P d istance to the capping atom 2.397 Angstrom (average) is significantly short er than the other W-P distance, 2.525 Angstrom (average).
