N-(2-Phenyl­imidazo[1,2-a]pyridin-3-yl)acetamide

The crystal structure of the title compound, C15H13N3O, consists of columns of mol­ecules that are inter­connected by N—H⋯N hydrogen bonds in the direction of the b axis. The torsion angle between the imidazo[1,2-a]pyridine ring system and the phenyl ring is 9.04 (5)°

2-Phenyl­imidazo[1,2-a]pyridine-3-carbaldehyde

In the title compound, C14H10N2O, the dihedral angle between the imidazo[1,2-a]pyridine and phenyl rings is 28.61 (4)° The mol­ecules 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 inter­actions between neighbouring pyridine rings, with a centroid–centroid distance of 3.7187 (7) Å
