2-{[(Pyridin-2-yl)amino]-meth-yl}phenol.

ABSTRACT: The planes of the aromatic rings of the title compound, C(12)H(12)N(2)O, are twisted by 50.33 (15)°. The phenol O atom is a hydrogen-bond donor to the pyridine N atom, resulting in the formation of an eight-membered ring in the mol-ecule. The amino N atom is a hydrogen-bond donor to the phenol O atom of an adjacent mol-ecule; this hydrogen bond leads to the formation of a helical chain that runs along the a axis.

2-[(Pyridin-3-yl-amino)-meth-yl]phenol.

Project description:In the title compound, C(12)H(12)N(2)O, the aromatic rings at either ends of the -CH(2)-NH- link are twisted by 68.79 (7)°. In the crystal, the hy-droxy substituent is a hydrogen-bond donor to the N atom of the pyridine ring of an adjacent mol-ecule, and the hydrogen bond generates a chain along the b axis; it is also a hydrogen-bond acceptor to the amino group of another adjacent mol-ecule. The two hydrogen bonds lead to the formation of a layer structure.

3-[(E)-(Pyridin-3-yl-imino)-meth-yl]phenol.

Project description:Two independent mol-ecules are present in the asymmetric unit of the title compound, C(12)H(10)N(2)O, in which the 3-hy-droxy-benzaldehyde and the pyridin-3-amine units are almost planar [r.m.s. deviations of 0.0236 and 0.0116Å, respectively, in one mol-ecule and 0.0245 and 0.0162Å, respectively, in the other] and are oriented at dihedral angles of 7.21 (7) and 14.77 (7)°. In the crystal, mol-ecules of the same type form inversion dimers via pairs of O-H⋯N hydrogen bonds, forming R(2) (2)(20) ring motifs. There exist π-π inter-actions between the benzene and pyridine rings of molecules of the same type with centroid-centroid distances of 3.7127 (10) and 3.8439 (10) Å.
