3-[5-(Pyridin-4-yl)-1,3,4-oxadiazol-2-yl]-4H-chromen-4-one

Abstract

In the title molecule, C16H9N3O3, the plane of oxadiazole ring is almost coplanar with attached pyridine ring and chromenyl ring system, forming dihedral angles of 2.37 (3) and 6.71 (2)°, respectively. In the crystal, a pair of C—H...O and C—H...N hydrogen-bond interactions lead to the formation of dimers, which are linked together into [100] chains.
