✦ Synopsis

The title molecule, C 20 H 24 N 2 , is centrosymmetric, crystallizing with the -N C(CH 3 )-C(CH 3 ) N-diimino group in a trans configuration. The crystal structure is stabilized by an intramolecular C-HÁ Á ÁN hydrogen-bonding interaction.

In the title compound, C 24 H 32 N 2 , there is one half-molecule in the asymmetric unit, the other half being generated by inversion. All bond lengths and angles show normal values. The deviation from a planar arrangement can be attributed to non-classical hydrogen bonds and steric factors.
