title: N-[Bis(morpholin-4-yl)phosphino-yl]-2-chloro-2,2-difluoro-acetamide.
abstract: The asymmetric unit of the title compound, C(10)H(17)ClF(2)N(3)O(4)P, consists of two independent mol-ecules in each of which the P atom adopts a distorted tetra-hedral environment with the P=O and N-H units in a syn orientation with respect to one another. Both morpholine rings in one of the phospho-ramide mol-ecules are disordered over two sets of sites, with site occupancies of 0.766 (7) and 0.234 (7) for one ring and 0.639 (10) and 0.361 (10) for the other. In the second phospho-ramide mol-ecule, one of the NC(4)H(8)O moieties is disordered over two sets of sites with site occupancies of 0.807 (6) and 0.193 (6). In the crystal, pairs of inter-molecular N-H⋯O(P) hydrogen bonds form two independent centrosymmetric dimers.
