2,2-Diphenyl-N-(2,4,5-trichloro-phen-yl)acetamide.

The asymmetric unit of the title compound, C(20)H(14)Cl(3)NO, consists of two independent mol-ecules. In one mol-ecule, the chlorinated benzene ring forms dihedral angles of 12.00 (9) and 77.04 (9)° with the phenyl rings. The dihedral angle between the phenyl rings is 80.37 (10)°. The corresponding dihedral angles for the other mol-ecule are 26.34 (10), 62.98 (10) and 88.47 (11)°, respectively. One of the mol-ecules features an intra-molecular C-H⋯O hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into [100] chains. The chains are further linked by C-H⋯O and C-H⋯Cl hydrogen bonds into a three-dimensional network.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
