| Abstract: | The i.r. spectra (4000-250 cm−1) of Cs3[VO(CN)5], [(C2H5)4N]3[VO(NCS)5], and K3 [ReO2(CN)4·2H2O have been obtained and empirical band assignments made. From a study of the v (CN) frequency it was possible to ascertain that metal-cyanide π-bonding is probably more important in VO(CN)53− than ReO2(CN)43−. Infrared evidence confirms the presence of N-bonded thiocyanate in VO(NCS)53−. The electronic spectra of the mulled solidssuggest that the lowest-energy transition in symmetrical VO2+ and trans-ReO2+ systems is similar. |
