The structure of the dichromium compound Cr 2(μ-OH) 2(μ-3,5Cl 2-form) 2(η 2-3,5Cl 2-form) 2

Abstract

With exposure to trace amounts of air and moisture, the Cr 2(II, II) complex Cr 2(μ-3,5Cl 2-form) 4, where 3,5Cl 2-form is [(3,5-Cl 2C 6H 3)NC(H)N(3,5-Cl 2C 6H 3) −], undergoes an oxidative addition reaction. Structural information from the X-ray crystal structure of the edge-sharing bioctahedral (ESBO) Cr 2(III, III) product Cr 2(μ-OH) 2(μ-3,5Cl 2-form) 2(η 2-3,5Cl 2-form) 2 ( 1) indicates 1 has a significantly longer Cr–Cr distance [2.732(2) Å] than Cr 2(μ-3,5Cl 2-form) 4 [1.9162(10) Å], but the shortest Cr–Cr distance in an ESBO Cr 2(III, III) complex recorded to date.
