Abstract: A second monoclinic polymorph of the title molecule, C₁₅H₂₁FN₃O₄P, is reported in the space group P2₁/n and compared to the previously reported C2/c space group [Gholivand et al. (2006). Polyhedron, 25, 711-721]. The asymmetric unit of the title compound consists of two independent molecules. The P atoms adopt a distorted tetrahedral environment. In the C(O)NHP(O) fragment, the P=O and the N-H groups are in a syn conformation with respect to each other and in the crystal, intermolecular N-HO=P hydrogen bonds form dimeric aggregates.
