Abstract

The dioxaphospho­lane ring in the title compound, C20H17O3P, adopts an envelope conformation about one of the ring carbons. The benzene rings of the compound do not form face-to-face π–π inter­actions, instead weak C—H⋯π inter­actions occur between adjacent mol­ecules. The methine H atoms on the dioxaphospho­lane ring form weak C—H⋯O hydrogen bonds to the oxide group of an adjacent mol­ecule.
