A redetermination of (2-methoxy­phen­yl)diphenyl­phosphine

The asymmetric unit of the title triphenyl­phosphine compound, C(19)H(17)OP, consists of two crystallographically independent mol­ecules with similar conformations. One of these two mol­ecules has a whole-mol­ecule disorder over two positions with refined occupancies of 0.753 (3) and 0.247 (3). The dihedral angles between the three benzene rings are 89.69 (7), 76.54 (7) and 86.02 (7)° in the non-disordered mol­ecule and the corresponding angles are 88.3 (4), 83.2 (4) and 84.2 (3)° for the major component and 80.2 (11), 89.5 (11) and 74.4 (9)° for the minor component of the disordered mol­ecule. This structure has been reported previously [Suomalainen et al. (2000 ▶). Eur. J. Inorg. Chem. pp. 2607–2613]; however, the disorder detailed here was not mentioned in that determination. In the crystal structure, the mol­ecules are stacked down the b axis and stabilized by C—H⋯π inter­actions.
