Abstract :
In the title racemic compound, C12H10ClNO, the dihedral angle between the
benzene and pyridine rings is 74.34 (6). In the crystal, the molecules are linked
by O—HN hydrogen bonds, forming zigzag C(5) [001] chains in which
alternating R- and S-configuration molecules are related by c-glide symmetry. In
addition, inversion-related pairs of molecules are linked into dimers by pairs of
weak C—Cl(pyridyl) interactions, which link the hydrogen-bonded chains
into (100) sheets. Structural comparisons are drawn with a number of related
compounds.
