Abstract

With exposure to trace amounts of air and moisture, the Cr₂(II, II) complex Cr₂(μ-3,5Cl₂-form)₄, where 3,5Cl₂-form is [(3,5-Cl₂C₆H₃) NC(H)N(3,5-Cl₂C₆H₃)^-], undergoes an oxidative addition reaction. Structural information from the X-ray crystal structure of the edge-sharing bioctahedral (ESBO) Cr₂(III, III) product Cr₂(μ-OH)₂ (μ-3,5Cl₂-form)₂(η² -3,5Cl₂-form)₂ (1) indicates 1 has a significantly longer Cr-Cr distance [2.732(2) Å] than Cr₂(μ-3,5Cl₂-form)₄ [1.9162(10) Å], but the shortest Cr-Cr distance in an ESBO Cr₂(III, III) complex recorded to date.
