The infrared spectra of some vanadium(V) peroxo complexes were measured and supplemented with published data ( a total of 33 complexes) to seek for relations between the stretching vibrations of the V(O2) group and the structure of the complexes. While no such relation could be established in the region of 9.10 - 800 cm-1, in the 660 - 490 cm-1 range the spectral patterns were found sensitive to the composition and structure of the coordination polyhedron, thus making it possible to discriminate between complexes of different types.
