Abstract
The title molecule, C22H16N2O4, is a 2,2′-disubstituted biphenyl whose phenylene rings are rotated by 66.5 (1)° so as to avoid repulsion by the substituents. Only one of the two amide –NH– fragments engages in hydrogen bonding, and this interacts with the amido –C(=O)– acceptor of an inversion-related molecule to generate a hydrogen-bonded dimer.
