英文摘要 | The Raman and infrared (IR) spectra of five multinuclear metal carbyne complexes of the type [Cl(CO)(2)(L)Wequivalent toCC(6)H(4)(Cequivalent toCC(6)H(4))(n)-Nequivalent toC-](m) M (M = PdI2 or ReCl(CO)(3)) I-V. and the pressure tuning Raman and IR spectra 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 nu(Wequivalent toC), a high-pressure sensitivity (dnu/dp = 0.75 cm(-1) kbar(-1)) was observed in the low-pressure phase, but a very low-pressure sensitivity (dnu/dp = 0.08 cm(-1) kbar(-1)) in the high-pressure phase. The substitution of two CO ligands in X(CO)(4)Wequivalent toCPh(R) by amine (TMEDA) or phosphine (DPPE) donor ligands causes a slight decrease of nu(Wequivalent toC) and a strong decrease of nu(Cequivalent toO).
