3‐Methyl‐7‐(2‐thienyl)pyrido[2,3‐d]pyrimidine‐2,4(1H,3H)‐dione: π‐stacked bilayers built from N—H...O,C—H...O and C—H...π hydrogen bonds

Abstract:In the title compound, C12H9N3O2S, the thienyl substituent is disordered over two sets of sites with occupancies of 0.749 (3) and 0.251 (3). A combination of N—H...O, C—H...O and C—H...π hydrogen bonds links the molecules into bilayers and these bilayers are themselves linked into a continuous structure by π–π stacking interactions.
