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—HN hydrogen bonds, which form R22(22) ring motifs and link the molecules into infinite chains running parallel to the a axis.
