[N,N′-Bis(2,4,6-trimethyl­phen­yl)ethane-1,2-diimine-κ²N,N′]tetra­carbonyl­chromium(0)

The octa­hedral coordination of the Cr⁰ atom in the title compound, [Cr(C₂₀H₂₄N₂)(CO)₄], displays some distortion. This is manifested by an exocyclic torsion angle C(mesitylene)—N—Cr—C(carbon­yl) that deviates by more than 20° from planarity. Another structural feature is the significant distortion from linearity of the Cr—C—O angles of the two carbonyl groups that inter­act with both ortho-methyl groups of the two mesitylene rings. The remaining two carbonyl groups overlap with the centres of the mesitylene rings themselves and are linear within <3°.
