The specific features revealed in the structure of the d 3 Cr(III), d 2 Cr(IV), d 1Cr(V), and d 0 Cr(VI) peroxo complexes with the ratios M:O2 = 1:1, 1:2, and 1:4 are considered. It is noted that, in eleven compounds of the general formula Cr(O2)nOm A p (n = 1, 2, 4; m = 0, 1; p = 0-4), the metal atoms can be in four oxidations states: +3 (d 3), +4 (d 4), +5 (d 1), and +6 (d 0). This property distinguishes chromium peroxo compounds from molybdenum and tungsten dioxygen complexes, which, with one exception, are represented by the d 0 M(VI) compounds. © 2007 Pleiades Publishing, Inc.
