Original language description

In the title compound, C42H46N2O4, both crystallographically independent molecules display a 1,3-alternate conformation. Their crystal packing is stabilized by non-classical C?H-N hydrogen bonds. The dihedral angles between the planes of the aromatic rings and the mean plane through the methylene C atoms bridging the aromatic rings are 78.10 (13), 80.74 (14), 81.89 (12) and 79.05 (14)_ for the first molecule, and 71.65 (11), 76.60 (13), 77.97 (14) and 74.76 (13) for the second molecule. Both molecules have three C atoms of one propoxy chain disordered over two set of sites; the site-occupancy factors are 0.7/0.3 and 0.6/0.4, respectively.
