Ethyl 9-fluoro-5,12-dioxo-5,12-dihydroindolizino[2,3-g]quinoline-6-carboxylate

Abstract

In the title molecule, C18H11FN2O4, the fused four- ring system is essentially planar, with an r.m.s. deviation of 0.032 Å. In the crystal, molecules are connected by π–π stacking interactions [centroid–centroid distances = 3.5684 (9) and 3.8247 (9) Å] into chains along [100].
