The Improved Synthesis of [Cr(N)(salen)].CH₃NO₂

In the title compound, {2,2'-[1,2-ethanediylbis(nitrilomethylidyne)]diphenolato-O,N,N',O'}nitridochromium(V) nitromethane solvate, [Cr(N)(C₁₆H₁₄N₂O₂)].CH₃NO₂, the metal center is five-coordinated. The chromium-nitride bond length is 1.559 (2) Å, which is 0.04 Å longer than in the analogous manganese(V) compound. The structure contains a co-crystallized nitromethane molecule. In line with its accepted weak-donor properties, this solvent molecule does not interact with the coordinatively unsaturated metal center.
