title: Crystal structure of (E)-4-[N-(7-methyl-2-phenyl-imidazo[1,2-a]pyridin-3-yl)carboximido-yl]phenol.
abstract: The mol-ecule of the title compound, C21H17N3O, is built up from fused five- and six-membered rings connected to a methyl group, a phenyl ring and an (imino-meth-yl)phenol group. The fused ring system is almost planar (r.m.s. deviation = 0.031 Å) and forms dihedral angles of 64.97 (7) and 18.52 (6)° with the phenyl ring and the (imino-meth-yl)phenol group, respectively. In the crystal, centrosymmetric mol-ecules are linked by pairs of C-H⋯π inter-actions into dimeric units, which are further connected by O-H⋯N hydrogen bonds to form layers parallel to (101).
