title: Bis(pyrrolidin-1-yl)phosphinic (2,4-di-fluoro-benzo-yl)amide.
abstract: The P atom in the title mol-ecule, C(15)H(20)F(2)N(3)O(2)P, is in a distorted tetra-hedral 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 R(2) (2)(8) ring motif.
