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.

Project description:In the title compound, C(20)H(15)F(2)NO, the mean plane of the acetamide group makes dihedral angles of 88.26?(6), 78.30?(7) and 9.83?(6)° with the two terminal benzene rings and difluoro-substituted benzene ring, respectively. One F atom is disordered over two orientations rotated by 180°, with a site-occupancy ratio of 0.557?(2):0.443?(2). An intra-molecular C-H?O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked via N-H?O hydrogen bonds into chains along the c axis. The crystal structure is further consolidated by C-H?? inter-actions.

Project description:The asymmetric unit of the title compound, [Ag(2)(C(2)ClF(2)O(2))(2)(C(25)H(22)P(2))(2)], consists of two half-mol-ecules, each Ag(I) ion lying on a center of symmetry.
