ABSTRACT
In the title compound, C(14)H(9)NO(2), the dihedral angle between the pyridine ring and the lactone ring is 10.40 (3)°. The coumarin ring system is nearly planar, with a dihedral angle of 1.40 (2)° between the lactone and benzene rings. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, inversion dimers linked by pairs of C-H⋯O inter-actions occur, generating R(2) (2)(14) loops.
