N,N′-(4,5-Dichloro-o-phenyl-ene)-dibenzamide

Abstract

In the title mol-ecule, C20H14Cl2N2O2, the dihedral angles between the central benzene ring and the two outer phenyl rings are 58.92 (7) and 21.91 (9)°. While an intra-molecluar N - H⋯O hydrogen bond may influence the mol-ecular conformation, an inter-molecular N - H⋯O hydrogen bond connects mol-ecules into centrosymetric dimers. © International Union of Crystallography 2007.
