RESUMO
In the title compound, C(16)H(13)N(3)O(4), the imidazo[1,2-a]pyridine and benzene rings make a dihedral angle of 56.21â (2)°. The crystal packing is stabilized by weak π-π stacking inter-actions [centroid-centroid distances = 3.787â (2)â Å] and C-Hâ¯O inter-molecular hydrogen-bonding inter-actions.
