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
摘要:
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 center dot center dot center dot O, C-H center dot center dot center dot O and C-H center dot center dot center dot pi hydrogen bonds links the molecules into bilayers and these bilayers are themselves linked into a continuous structure by pi-pi stacking interactions.
