Bis(pyrrolidin-1-yl)phosphinic (2,4-di­fluoro­benzo­yl)amide

The P atom in the title mol­ecule, C₁₅H₂₀F₂N₃O₂P, is in a distorted tetra­hedral P(O)(N)(N)₂ environment. The phosphoryl group and the NH unit adopt a syn orientation with respect to each other. An F atom at position 2 and an H atom at position 6 are found to occupy similar sites in a 0.70:0.30 ratio and were refined with fixed occupancies. The pyrrolidin-1-yl rings are disordered over two sets of sites, with site occupancies of 0.566 (6) and 0.434 (6), and were refined using a two-part model. In the crystal, hydrogen-bonded dimers linked by pairs of N—H...O(P) hydrogen bonds generate an R₂²(8) ring motif.
