Fig. 5. (a) Variable temperature solid state UV-vis spectra of 1(Pd)·2H2O (orange) and 1(Pd) (purple). The arrow indicates the direction of the spectral change with heating to the dehydrated material. Inset: photograph of a capillary showing the difference in colour of 1(Pd)·2H2O (yellow) and 1(Pd) (pink). (b) Observed Raman spectra of 1(Pd) in the HS (orange) and LS (purple) states showing the difference in the alkyne and cyanide stretching bands.
