The title compound, C(36)H(28)O(4)P(2).CH(4)O, was synthesized directly from the methoxy analogue. The crystal structure shows that one OH group interacts with an O atom of a phosphine oxide group in an adjacent molecule, while the other OH group complexes with the methanol solvent molecule via intermolecular hydrogen bonds. An O atom of one phosphine oxide group interacts with the hydroxy H atom of methanol via a hydrogen bond. There are intra- and intermolecular pi-pi interactions between the phenyl rings. All these interactions result in the formation of supramolecular chiral parallelogram channels via self-assembly.
