Abstract
[WBr2(CO)(PPh2Cy)(2)(eta(2)-MeC2Me)]. CH2Cl2 (Cy = cyclohexyl) crystallizes in the mono clinic space group, P2(1)/n, with a = 10.606(12), b = 23.11(3) , c = 18.19(2) Angstrom, beta = 106.070(10) D-calc = 1.610g cm(-3) for Z = 4. The tungsten coordination geometry can best be considered as a distorted octahedron, with the but-2-yne ligand occupying one coordination site, whi ch has a trans-Br(2) group. The equatorial plane is made up of trans-PPh2Cy groups, with the bromo and carbonyl ligands occupying the other two sites.
