Abstract: | The molecules of 8‐methyl‐7,10‐diphenyl‐5H‐benzoh]pyrazolo3,4‐b]quinoline‐5,6(10H)‐dione, C27H17N3O2, (I), are weakly linked into chains by a single C—H...O hydrogen bond, and these chains are linked into sheets by a π–π stacking interaction involving pyridyl and aryl rings. In 8‐methyl‐7‐(4‐methylphenyl)‐10‐phenyl‐5H‐benzoh]pyrazolo3,4‐b]quinoline‐5,6(10H)‐dione, C28H19N3O2, (II), the molecules are linked into a three‐dimensional framework structure by a combination of C—H...N, C—H...O and C—H...π(arene) hydrogen bonds, together with a π–π stacking interaction analogous to that in (I). |
