title: rac-Dimethyl [(9-anthr-yl)(4-methyl-anilino)meth-yl]phospho-nate.
abstract: The title compound, C(24)H(24)NO(3)P, crystallizes as a racemate with two mol-ecules in the asymmetric unit. The structural features (bond lengths and angles) of the two mol-ecules are almost identical. The dihedral angle between the anthracene and toluidine rings is similar in the two mol-ecules, with values of 48.36 (9) and 51.15 (9)°. The methyl groups of one of the meth-oxy groups in one mol-ecule is disordered over two sets of sites, the major component having a site occupancy of 0.636 (3). In the crystal, both molecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds.
