Hexacarbonyl(η^5:1-2-cyclopentadienediylethyl)(μ-η^1:3-1-ethoxy-2-propenylidene)molybdenumtungsten

The crystal structure of the title compound [alternative nomenclature: hexacarbon-1κ⁵C, 2κC-2(η⁵)-2-cyclopentadiendiylethyl-2κC¹-μ-2(η²)-1-ethoxy-2-propenylidene-1:2κ²C¹-2-molybdenum-1-tungsten(Mo-W)], [(C₅H₄C₂H₄)(CO)Mo(C₃H₃OC₂H₅)W(CO)₅], (I), has been determined from single-crystal X-ray diffraction data. Geometry and bond lengths of (I) are in accord with a description as a 1-molybdena-5-tungstenatricyclo [2,1,0,0^1,3]pentane or, even better, as an arachno-pentagonal bipyramid with a Mo atom at the apex.
