4-{4-[(E)-(2-Hy-droxy-phen-yl)imino-methyl]phen-oxy}benzene-1,2-di-carbo-nitrile.

ABSTRACT: The asymmetric unit of the title compound, C(21)H(13)N(3)O(2), contains two independent mol-ecules with a similar structure. In one mol-ecule, the central benzene ring is oriented with respect to the terminal benzene rings at 27.23?(7) and 67.96?(7)°; in the other mol-ecule, the corresponding dihedral angles are 12.42?(7) and 64.55?(7)°. In both molecules, there is a short O-H?N interaction involving the OH group and the adjacent N atom. In the crystal, there are O-H?N hydrogen bonds, and C-H?O and N-H?O interactions linking the molecules to form a three-dimensional network. ?-? stacking between the pyridine and benzene rings and between the benzene rings [centroid-centroid distances = 3.989?(2), 3.705?(2) and 3.607?(2)?Å] may further stabilize the structure. A weak C-H?? inter-action is present in the crystal.
