Abstract: The title compound, C12H10N2O, a second monoclinic polymorph of (E)-phenyl(pyridin-2-yl)methanone oxime crystallizes in the space group P21/n (Z = 4). The previously reported polymorph [Taga et al. (1990). Acta Cryst. C46, 2241-2243] occurs in the space group C2/c (Z = 8). In the crystal, pairs of bifurcated O-H...(N,O) hydrogen bonds link the molecules into inversion dimers. The dimers are linked by C-H...[pi] interactions, forming a linear arrangement. The dihedral angle between the pyridine and phenyl rings is 67.70 (8)°.
