2-[(4-Meth-oxy-benz-yl)imino-meth-yl]phenol.

In the title Schiff base compound, C(15)H(15)NO(2), prepared from 4-meth-oxy-benzyl-amine and salicyl-aldehyde, an intra-molecular O-H⋯N hydrogen bonds influences the mol-ecular conformation; the two aromatic rings form a dihedral angle of 73.5 (1)°. In the crystal, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into chains propagating in [010].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
