The UV photoelectronspectra of tris(butadiene)molybdenum and -tungsten have been recorded and assigned with the assistance of extended Hückel molecular orbital calculations. The spectra and calculations indicate substantial electron transfer from the metal to the ligand. The molecular orbital calculations have also indicated why these molecules adopt a trigonal prismatic rather than a octahedral geometry

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 diene unit displaying a long—short—long bond alternation, and having short
