A second monoclinic polymorph of (E)-phen­yl(pyridin-2-yl)methanone oxime

The title compound, C(12)H(10)N(2)O, a second monoclinic poly­morph of (E)-phen­yl(pyridin-2-yl)methanone oxime crystallizes in the space group P2(1)/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...

Sumario:The title compound, C(12)H(10)N(2)O, a second monoclinic poly­morph of (E)-phen­yl(pyridin-2-yl)methanone oxime crystallizes in the space group P2(1)/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⋯π inter­actions, forming a linear arrangement. The dihedral angle between the pyridine and phenyl rings is 67.70 (8)°.
