Abstract
In the title compound, C 18 H 29 N 5 O 3 , each piperazine ring assumes a «perfect chair» conformation with the exocyclic methyl group in an equatorial position. The nitro group makes a dihedral angle of 5.5 (1) o with the mean plane of the phenyl ring. Best planes through the four non-N atoms of each of the two piperazine rings make a dihedral angle of 29.9 (1) o with one another
