Tris(substituted butadiene) complexes of molybdenum and tungsten have been prepared by the reduction of the metal halides with anthracene-activated magnesium in the presence of the appropriate diene.An X-ray diffraction study has shown tris(2,3-dimethylbutadiene)molybdenum and its tungsten analogue to be isomorphous, with each unit displaying a long-short-long bond alternation, and having short metal to terminal carbon atom distances, in marked contrast to the unsubstituted complexes.
