7-Methyl-3,7,11,17-tetraazabicyclo[11.3.1]heptadeca-1(17),13,15-triene

The title compound, C₁₄H₂₄N₄, is known to act as a macrocyclic ligand and its conformation has been determined to facilitate future comparisons with its coordinated forms. The alphatic macrocyclic strand is disordered with respect to a mirror plane perpendicular to the pyridine ring and containing the ordered tertiary N atom; the four donor N atoms are approximately coplanar.
