In the centrosymmetric title compound (dtne), C14H32N6, two 1,4,7-triazacyclononane (tacn, or 1,4,7-triazonane) moieties are linked together each at an amino position by a single ethylene spacer. The molecular packing is supported by pairs of intermolecular N—H⋯N hydrogen bonds, which form R22(22) ring motifs and link the molecules into infinite chains running parallel to the a axis.
