Abstract

The Raman and infrared (IR) spectra of five multinuclear metal carbyne complexes of the type of one representative complex III, were studied. The high pressure study on complex III reveals the presence of a pressure-induced phase transition near 20 kbar. For v(W≡C), a high-pressure sensitivity (dv/dp = 0.75 cm^-1 kbar^-1) was observed in the low-pressure phase, but a very low-pressure sensitivity (dv/dp = 0.08 cm^-1 kbar^-1) in the high-pressure phase. The substitution of two CO ligands in X(CO)₄W≡CPh(R) by amine (TMEDA) or phosphine (DPPE) donor ligands causes a slight decrease of v(W≡C) and a strong decrease of v(C≡O).
