The complete molecule of the title compound, C19H32S2, is generated by crystallorgaphic twofold symmetry, with three C atoms lying on the axis. The Car—C—S—C (ar = aromatic) torsion angle is 156.2 (2) °. In the crystal, the molecules are linked by very weak C—H
S interactions, generating [001] chains.

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—Hπ interactions, forming a linear arrangement. The dihedral angle between the pyridine and phenyl rings is 67.70 (8)°.
