The title compound, C12H28N6, is located about an inversion center situated at the center of the —CH2—CH2— bond. The C—N bond lengths are 1.285 (2), 1.384 (2) and 1.395 (1) Å, indicating double- and single-bond character. The N—C—N angles are 114.1 (1), 119.3 (1) and 126.5 (1)°, showing a deviation of both CN3 planes from an ideal trigonal–planar geometry.
