Crystal structure of (E)-4-[N-(7-methyl-2-phenyl­imidazo[1,2-a]pyridin-3-yl)carboximido­yl]phenol

The mol­ecule of the title compound, C(21)H(17)N(3)O, is built up from fused five- and six-membered rings connected to a methyl group, a phenyl ring and an (imino­meth­yl)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 (imino­meth­yl)phenol group, respectively. In the crystal, centrosymmetric mol­ecules are linked by pairs of C—H⋯π inter­actions into dimeric units, which are further connected by O–H⋯N hydrogen bonds to form layers parallel to (101).
