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
钼和钨的三(取代丁二烯)配合物是通过在适当的二烯存在下用蒽活化的镁还原金属卤化物而制得的。X射线衍射研究表明,三(2,3-二甲基丁二烯)钼及其钨类似物是同构的,每个二烯单元显示长-短-长键交替,并且金属到末端碳原子的距离短。与未取代的配合物形成明显对比。
