Notes:
In the crystal structure of the title compound, C14H12N2O2, the molecule lies about a twofold axis; two carbonyl groups and the H atoms of the N—N bond are in a trans orientation with respect to each other. In the crystal, each molecule is linked to the other and vice versa by intermolecular N—H...O hydrogen bonds between the amide hydrogen and the O atoms of neighbouring molecules to form two ten-membered rings, each of which has the graph-set motif C4R{_2^2}(10). This extends as a polymeric chain along the c axis.
