2,2′-[Octane-1,8-diyldioxybis(nitrilomethylidyne)]diphenol

Abstract

The complete molecule of the title compound, C22H28N2O4, is generated by a crystallographic inversion centre at the mid-point of the central C—C bond. The two benzene rings are parallel to each other with a perpendicular interplanar spacing of 1.488 (2) Å. Intramolecular O—H...N hydrogen bonds generate two six-membered rings with S(6) motifs. In the crystal, weak intermolecular C—H...O hydrogen bonds link neighbouring molecules into an infinite three-dimensional network, which is further stabilized by weak C—H...π interactions.
