X-Ray analysis was carried out of 4,4-diphenyl-1-(2,4,6-tri-t-butylphenyl)-1-phospha-1,2,3-butatriene as a ligand of pentacarbonyltungsten complex.The heterocumulene system was found to be planar with a rod framework coordinating to the tungsten metal at the phosphorus atom in a ?-type coordination.
