4-(2-Fluoro-pyridin-5-yl)phenol.

ABSTRACT: In the title compound, C(11)H(8)FNO, the aromatic rings are oriented at a dihedral angle of 31.93 (6)°. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming C(9) chains propagating along the c-axis direction. There are aromatic π-π stacking inter-actions between the pyridine rings [centroid-centroid separation = 3.7238 (16) Å].

2-Fluoro-6-[(E)-(pyridin-2-yl)imino-meth-yl]phenol.

Project description:The title compound, C(12)H(9)FN(2)O, is almost planar (r.m.s. deviation for the 16 non-H atoms = 0.019?Å), a conformation stabilized by an intra-molecular O-H?N hydrogen bond, which generates an S(6) ring. In the crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds generate R(2) (2)(16) loops.

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.

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

Project description: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.

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.

4-Bromo-2-{[(pyridin-3-ylmeth-yl)imino]-meth-yl}phenol.

Project description:The title compound, C(13)H(11)BrN(2)O, is a polydentate Schiff base and reveals intra-molecular O-H⋯N hydrogen bonding between the hy-droxy O atom and the imino N atom. The dihedral angle between the aromatic ring and the pyridyl ring is 71.7 (1)°. In the crystal, the mol-ecules are stacked in columns along the c axis and several inter-molecular π-π inter-actions are present between the six-membered rings, with a shortest centroid-centroid distance of 3.707 (2) Å.

Project description:In the title compound, C19H14FN3, the dihedral angles between the benzimidazole unit (r.m.s. deviation= 0.017 Å) and the pyridine and benzene rings are 24.46 (4) and 81.87 (3)°, respectively.

2-[({[Bis(pyridin-2-yl)methylidene]hydrazinecarbonyl}hydrazinylidene)(pyridin-2-yl)methyl]pyridinium tetra-fluoro-borate.

Project description:In the title compound, C(23)H(19)N(8)O(+)·BF(4) (-), one pyridine N atom is protonated. Two intra-molecular N-H?N hydrogen bonds occur. In the crystal, inter-molecular N-H?N hydrogen bond links neighboring C(23)H(19)N(8)O(+) units into cyclic supra-molecular dimers while C-H?O hydrogen bonds link the C(23)H(19)N(8)O(+) units into a two-dimensional supra-molecular network structure.

4-Fluoro-2-[(3-methyl-phen-yl)imino-meth-yl]phenol.

Project description:The title compound, C(14)H(12)FNO, crystallizes as the trans phenol-imine tautomer. The two benzene rings are essentially coplanar, being inclined to one another by 9.28?(7)°. This is at least in part due to the intra-molecular O-H?N hydrogen bond between the hy-droxy O atom and the imine N atom. The crystal structure is stabilized by an array of weak C-H?O and C-H?F inter-actions, which link the mol-ecules into a stable three-dimensional network.
