2-(2-Hydroxy-benzyl-ideneamino)benzonitrile.

ABSTRACT: The mol-ecule of the title compound, C(14)H(10)N(2)O, displays a trans configuration with respect to the C=N double bond. The mol-ecule is roughly planar; the two aromatic rings make a dihedral angle of 9.3?(3)°. Such a planar conformation is induced by the strong intra-molecular O-H?N hydrogen bond between the imine and hydroxyl groups.

The mol-ecule of the title compound, C(14)H(10)N(2)O, displays a trans configuration with respect to the C=N double bond. The mol-ecule is roughly planar; the two aromatic rings make a dihedral angle of 9.3 (3)°. Such a planar conformation is induced by the strong intra-molecular O-H⋯N hydrogen bond between the imine and hydroxyl groups. ...[more]

Project description:In the title compound, [Zn(H(2)O)(6)](C(13)H(10)NO(4)S)(2), a distorted ZnO(6) octa-hedron results from the coordination by the six water mol-ecules.

(E)-2-[(3,5-Di-tert-butyl-2-hydroxy-benzyl-idene)amino]benzonitrile.

Project description:The asymmetric unit of the title compound, C(22)H(26)N(2)O, contains three crystallographically independent mol-ecules, in which the aromatic rings are oriented at dihedral angles of 21.74?(5), 27.59?(5) and 27.87?(5)°. Intra-molecular O-H?N hydrogen bonds result in the formation of planar six-membered rings, and these are nearly coplanar with the adjacent rings. In the crystal structure, ?-? contacts between the benzene rings [centroid-centroid distances = 3.989?(2), 3.802?(1) and 3.882?(1)?Å] may stabilize the structure.
