Tris(2-methoxy-phen-yl)phosphine.

In the title compound, C(21)H(21)O(3)P, the whole mol-ecule is disordered over two sets of positions with refined occupancies of 0.503 (1) and 0.497 (1). The dihedral angles between the three benzene rings are 72.9 (2)°, 82.9 (3)° and 70.0 (2)° in the major disorder component and the corresponding angles in the minor disorder component are 85.0 (2)°, 79.2 (2)° and 72.3 (2)°. The crystal structure is stabilized by C-H⋯π inter-actions.
