14,54-Dichloro-3(2,7),7(2,7)-dinaphthalena-2,4,6,8-tetraoxa-1(2,6),5(2,6)-di(1,3,5-triazina)octaphane

Abstract

In the macrocyclic title compound, C26H12Cl2N6O4, an O-atom-bridged calix[2]naphthalene[2]triazine synthesized using a one-pot approach from naphthalene-2,7-diol and cyanuric chloride, the two isolated naphthalene planes and the two triazine-2,6-dioxy planes adopt a 1,3-alternate configuration, with a dihedral angle of 84.10 (8)° between the naphthalene rings and a dihedral angle of 39.02 (14)° between the triazine rings. In the crystal, weak intermolecular π–π stacking interactions are found between face-to-face naphthalene rings [centroid–centroid distance = 3.662 (7) Å].
