Abstract: The crystal structure of the title compound, MeNC4H8NMe or C6H14N2, which is liquid under ambient conditions, has been determined at low temperature. The molecule occupies a special position on a crystallographic inversion centre. The piperazine ring has an almost ideal chair conformation, with the absolute values of the endocyclic torsion angles in the range 57.4-58.6°. No close C-HN contacts are observed in the crystal structure.
