A redetermination of (2-methoxy-phen-yl)diphenyl-phosphine

Abstract

The asymmetric unit of the title triphenyl-phosphine compound, C 19H17OP, consists of two crystallographically independent mol-ecules with similar conformations. One of these two mol-ecules has a whole-mol-ecule 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 mol-ecule 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 mol-ecule. 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 mol-ecules are stacked down the b axis and stabilized by C- H⋯π inter-actions.
