The 12H11NO2, represents a new orthorhombic polymorph II of the previously reported orthorhombic form I [Zhang et al. (2009) Acta Cryst. E65, o3160]. In polymorph II, the six-membered rings form a dihedral angle of 13.8 (1)° [71.6 (1)° in I], and O—H⋯N hydrogen bonds link molecules into chains along [100], whereas the of I features hydrogen-bonded centrosymmetric dimers.

The 2-(pyridin-4-ylmethoxy)phenol was synthesized by the reaction of o-benzenediol and 4-chloromethylpyridine hydrochloride under nitrogen atmosphere and alkaline condition (Gao et al., 2004). Colourless block crystals were obtained by slow evaporation of a methanol solution (10 mL) containing title compound (0.402 g, 2 mmol) and (R)-2-(4-(carboxymethoxy)phenoxy)propanoic acid (0.48 g, 2 mmol) which only contained the molecules of title compound.
H atoms bound to C atoms and the H atoms of the hydroxyl groups were placed in calculated positions and treated as riding on their parent atoms, with C—H = 0.93 Å (aromatic), C—H = 0.97 Å (methylene), O—H = 0.82 Å and with Uiso(H) = 1.2Ueq(C), Uiso(H) = 1.5Ueq(O).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The reported here crystal structure of the title compound, C12H11NO2, represents a new orthorhombic polymorph (II)of the previously reported orthorhombic form (I) (Zhang et al. 2009). It was crystalized from a methanol solution of the title compound and (R)-2-(4-(carboxymethoxy)phenoxy)propanoic acid mixture.
In polymorph II (Figure 1), two six-membered rings form a dihedral angle of 13.8 (1)° [71.6 (1)° in I], and intermolecular O—H···N hydrogen bonds link molecules into chains along [100] (Figure 2, Table 1), in spite of hydrogen-bonded centrosymmetric dimers in polymorph I.
