Revealing redox isomerism in trichromium imides by anomalous diffraction.

ABSTRACT: In polynuclear biological active sites, multiple electrons are needed for turnover, and the distribution of these electrons among the metal sites is affected by the structure of the active site. However, the study of the interplay between structure and redox distribution is difficult not only in biological systems but also in synthetic polynuclear clusters since most redox changes produce only one thermodynamically stable product. Here, the unusual chemistry of a sterically hindered trichromium complex allowed us to probe the relationship between structural and redox isomerism. Two structurally isomeric trichromium imides were isolated: asymmetric terminal imide (^tbsL)Cr₃(NDipp) and symmetric, μ³-bridging imide (^tbsL)Cr₃(μ³-
