Abstract: The title compound, C40H40N4O4, contains a 1,4,8,11-tetraazacyclotetradecane ring, with four benzyl and two methylene substituents and also four carbonyl groups. This molecule is only the second reported structure of the 1,4,8,11-tetraazacyclotetradecane ring with four carbonyl groups on C atoms 2, 3, 9 and 10. Large-ring nitrogen heterocycles are often useful for their ability to selectively coordinate with certain metal ions, and are also sometimes used as precursors to new energetic materials. In the crystal structure the molecule is centrosymmetric.
