4,5-Dimethyl-1,2-bis(pyridine-3-carbox-amido)-benzene

Abstract

In the title mol-ecule, C20H18N4O2, the dihedral angles between the central benzene ring and the two pyridine rings are 12.07 (8) and 4.80 (1)°, and that between the two pyridine rings is 16.78 (9)°. An intra-molecular N - H⋯O hydrogen bond may influence the mol-ecular conformation. In the crystal structure, inter-molecular N - H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers, while weak inter-molecuar C - H⋯O hydrogen bonds link these dimers into one-dimensional chains. © International Union of Crystallography 2007.
