4-[2-(4-Fluoro-phen-yl)furan-3-yl]pyridine.

Project description:In the crystal structure of the title compound, C(15)H(10)FNO, the furan ring makes dihedral angles of 40.04?(11) and 25.71?(11)° with the pyridine and 4-fluoro-phenyl rings, respectively. The pyridine ring makes a dihedral angle of 49.51?(10)° with the 4-fluoro-phenyl ring. Non-conventional C-H?F and C-H?N hydrogen bonds are effective in the stabilization of the crystal structure.

2-Vinyl-pyridine-tris-(penta-fluoro-phen-yl)borane hexane monosolvate.

Project description:The title compound, C(7)H(7)N·B(C(6)F(5))(3)·C(6)H(14), was obtained by the stoichiometric reaction of 2-vinyl-pyridine and tris-(penta-fluoro-phen-yl)borane in toluene. The formed adduct exhibits a restricted rotation along the B-N bond resulting in an asymmetry, which can be also observed in the (19)F NMR spectra. The B-N distance is equivalent to the distances found for 2-methyl-pyridine and 2-ethyl-pyridine B(C(6)F(5))(3) adducts. For the final refinement, the contributions of disordered solvent mol-ecules were removed from the diffraction data with SQUEEZE in PLATON [van der Sluis & Spek (1990). Acta Cryst. A46, 194-201; Spek (2009). Acta Cryst. D65, 148-155].

2-Amino-4-(3-fluoro-phen-yl)-6-(naphthalen-1-yl)pyridine-3-carbonitrile.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(22)H(14)FN(3), which differ slightly in the relative orientations of the naphthyl and phenyl groups with respect to the pyridyl ring framework. In one mol-ecule, the naphthyl ring system and the phenyl ring form dihedral of angles 56.50?(2) and 48.23?(3)°, respectively, with the pyridyl ring plane. In the other mol-ecule, the corresponding dihedral angles are 50.01?(2) and 51.1?(3)°, respectively. In the crystal, inter-molecular N-H?N hydrogen bonds connect the independent mol-ecules into dimers.
