The title compound, C24H16N2O4 (systematic name: 2,6-dibenzylpyrrolo[3,4-f]isoindole-1,3,5,7(2H,6H)-tetraone), lies about a crystallographic inversion center at the center of the pyromellitic diimide moiety which is planar. In the crystal, intermolecular C—H
O hydrogen bonds and C—H
π interactions lead to the formation of a two-dimensional supramolecular network.

The influence of pH on the solvothermal reaction of Cu(NO3)2·3H2O, Na2(C2O4) and the N,N′-ditopic organic ligands 1-(pyridin-4-yl)piperazine and 1,2-bis(pyridin-4-yl)ethane has been studied. For an acidic pH value of 2, a one-dimensional zigzag chain structure and a discrete ionic structure, respectively, were obtained.

The intramolecular conformational response to the build-up of compressed intermolecular interactions in Blatter's radical (1,3-diphenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl) induces a second-order premonitory phase transition and then a first-order phase transition above 5.34 GPa.
