摘要

The complex [WI(CO)(cis-dppen)(#eta#~2-MeC_2Me)_2]I centre dot CH_2Cl_2(1) is prepared as a by-product from the reaction of equimolar quantities of [WI_2(CO)(NCMe)(#eta#~2-MeC_2Me)_2] and cis-dppen {dppen = bis(diphenylphosphino)ethene}. Complex 1, [WI(CO)(cis-dppen)(#eta#~2-MeC_2Me)_2]I centre dot CH_2Cl_2 crystallizes in the triclinic space group P1-bar with a = 11.189(13), b = 12.331(14), c = 15.395(17) A, #alpha# = 83.61(1), #beta# = 86.06(1), #gamma# = 64.48(1) deg, U = 1904 A~3, and Z = 2. The metal environment in the cation can best be considered as a distorted octahedron with the two but-2-yne groups taking up individual sites trans to phosphorus atoms of the dppen ligand. The coordination sphere is completed by mutually trans-carbonyl and iodide groups.
