    Notes: Abstract [WI2(CO)3{P(OMe)3}2]crystallizes in the orthorhombic space group Pca21, with a = 26.924(5), b = 10.726(2), c = 14.136(3) Å, and Z = 8. There are two molecules in the asymmetric unit, the metal atoms in each case being seven-coordinate with a capped fac-(CO)3 octahedral geometry. The molecular dimensions in the two molecules are nearly identical. The W–P distance to the capping atom 2.397 Å (average) is significantly shorter than the other W–P distance, 2.525 Å (average).

    Notes: Abstract [WI2(CO)2{P(OiPr)3}(η2-EtC2Et)] crystallizes in the monoclinic space group P21/n, with a = 11.101(12), b = 16.272(18), c = 14.892(17) Å, β = 93.27(1), Z = 4. The geometry can be considered to be pseudo-octahedral, with the 3-hexyne ligand occupying one site, with two iodo-groups, and the P(OiPr)3 ligand completing the equational plane of ligands, with two trans-carbonyl groups occupying the axial sites.
