Crystal structure of 26-(4-methylphenyl)-8,11,14,17-tetraoxa-28-azatetracyclo[22.3.1.02,7.018,23]hexacosa-2,4,6,18(23),19,21,24(1),25,27-nonaene

The title compound, C30H29NO4, is a tetracyclic system containing a 4-arylpyridine fragment, two benzene rings and an aza-17-crown-5 ether moiety, in a bowl-like arrangement. The pyridine ring is inclined to the 4-methylphenyl ring by 26.64(6)°, and by 57.43(6) and 56.81(6)° to the benzene rings. The benzene rings are inclined to one another by 88.32(6)°. In the crystal, molecules are linked by pairs of C - H⋯N hydrogen bonds, forming inversion dimers with an R 2 2(14) ring motif. The dimers are linked via a number of C - H⋯π interactions, forming a three-dimensional architecture. © 2016.
