Abstract
The title compound, C62H72N4O8, has a cone conformation. The planes of the individual phenyl rings are inclined at angles of 97.49(7), 142.2 4(10), 92.78(7) and 143.14(11)degrees to the plane of the methylene C atoms linking these aromatic rings. There are intramolecular hydrogen bonds between the proximal hydroxy and ether functional groups, with O ... O non-bonded contacts of 2.862(3) and 2.892(3)Angstrom, respectiv ely. The cones are linked to one another along the a axis by two weak intermolecular C-H ... O hydrogen bonds [C ... O contacts of 3.303 (7) and 3.377 (7) Angstrom] to form an infinite polymeric chain.
