Abstract: In the title compound, [Al₂(CH₃)₆(C₂₁H₂₈N₂)], the piperazine ring adopts a chair conformation. The Al-N bond lengths range from 2.089 (2) to 2.121 (2) Å. The four-coordinate environment of the Al atoms is defined by one piperazine N atom and three methyl ligands. The structure contains two independent molecules in the asymmetric unit. Both molecules have almost the same conformation, except for the benzyl groups which show different rotations in the two molecules. The independent molecules are related to one another by a pseudorotation in combination with a translation along the a axis. Intermolecular C-H contacts or stacking between the benzyl or phenyl rings are not observed.
