1,1'-Diacetyl-2,2'-biimidazole

A crystallographic twofold rotation axis passes through the C-C bond joining the imidazole rings of the title compound, C₁₀H₁₀N₄O₂. The molecule crystallizes in a cis disposition. The planar acetyl group is twisted by 5.0 (3)° with respect to the imidazole ring and the two imidazole rings are tilted by 60.53 (5)° in relation to one another.
