Studies of Mixed-valence Compounds（Ⅰ）──In-Situ FTIR and UV-Visible-Near-IR Spectroelectrochemical Studies of Mixed-valence Isopolyanion Mo6O193- in Aprotic Media

The mixed-valence isopolyanion Mo6O193- was investigated by means of cyclic voltammographic, in-situ FTIR and UV-Visible-Near-IR spectro-electrochemicalmethods in aprotic media. The experimental results indicate that the Mo6O193-was formed whereafter Mo6O193- was reduced, (E0’ = - 0. 690 V, n = 1 ). The characteristic absorptions of Mo6O193- are 500 nm, 900 nm and 1100 nm in UV-VisibleNear-IR spectrum and 940 cm-1 in IR spectrum.
