Abstract

The racemic title compound, C27H26N2O4, crystallizes with its central carbon bridge on a twofold axis. It forms parallel chains of molecules utilizing aryl offset face–face interactions with an interplanar distance of about 3.5 Å. These chains associate further by means of pairs of O—CH2—H...π (with H–ring distances ranging from 2.69 to 2.95 Å) and O—CH2—H...N motifs. The methoxy groups in this structure are coplanar with the aromatic rings to which they are attached. This is recognized as being common behaviour amongst aromatic methoxy compounds.
