چکیده
In the title compound, C(14)H(10)N(2)O, the dihedral angle between the imidazo[1,2-a]pyridine and phenyl rings is 28.61 (4)° The mol-ecules are connected into broad chains parallel to the a axis by weak C-H⋯O and C-H⋯N hydrogen bonds. The linking of the ribbons is provided by π-π stacking inter-actions between neighbouring pyridine rings, with a centroid-centroid distance of 3.7187 (7) Å.
