4-Benzoyl-4-(2-cyanoethyl)heptanedinitrile at 143K

The title compound, C₁₇H₁₇N₃O, crystallizes with two molecules in the asymmetric unit, which differ significantly only in the conformation of one torsion angle. All bonds between the methylenic C atoms except one, which is synclinal, display antiperiplanar conformations. The carbonyl bond is twisted by 32° out of the plane of the phenyl ring and synperiplanar to one of the methylenic C atoms.
