摘要：

The Raman and IR spectra of 1,1-bis[diphenylphosphino]ethene (Ph2P)(2)C=CH2 (vdpp) and the tetracarbonyl tungsten complex (vdpp)W(CO)(4) have been recorded. Vibrational assignments are proposed based on local symmetry considerations. For the vinylidene stretching mode a coordination shift is observed from 1588 cm(-1) in polycrystalline vdpp to 1581 cm(-1) in its tetracarbonyl tungsten complex. From a comparison of the v(CO) splitting pattern with those of related complexes monoclinic structure with factor group C-2h and four formula units per unit cell is concluded.
