The asymmetric unit of the title compound, C13H14O3, contains two independent mol-ecules, A and B, that are inter-connected through an offset π-π inter-action [inter-centroid separation = 3.6087 (4) Å]. The fused benzene and pyran-2-one rings in each mol-ecule are essentially coplanar, having dihedral angles of 1.

The title compound, C(15)H(17)O(6)P, was obtained from a reaction of 4-methyl-7-hy-droxy-coumarin and 2-chloro-5,5-dimethyl-1,3,2-dioxaphosphinane 2-oxide. There are two mol-ecules in the asymmetric unit in which the benzopyran ring system is almost planar [r.m.
