2-Amino-4-(4-bromo-phen-yl)-6-ferro-cenyl-pyridine-3-carbonitrile.

ABSTRACT: The title compound, [Fe(C(5)H(5))(C(17)H(11)BrN(3))], was synthesized by the reaction of 4-bromo-benzaldehyde, acetyl-ferrocene and ammonium acetate in an aqueous medium. The crystal packing is stabilized by inter-molecular N-H⋯N hydrogen bonds. The dihedral angles between the phenyl ring and the pyridine and cyclopentadienyl rings are 51.67 (13) and 12.12 (21)°, respectively.

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.

2-Amino-4-(4-chloro-phen-yl)-4H-chromeno[8,7-b]pyridine-3-carbonitrile.

Project description:The asymmetric unit of the title compound, C19H12ClN3O, contains two mol-ecules with similar conformations. The 14 non-H atoms comprising the 4H-chromeno[8,7-b]pyridine residue are essentially coplanar (r.m.s. deviations = 0.037 and 0.042?Å for the two mol-ecules) and the main difference between them is seen in the twist about the bond linking the main residue to the attached chloro-benzene rings [dihedral angles = 79.01?(12) and 76.22?(11)° for the two mol-ecules]. Zigzag supra-molecular chains along the a-axis direction mediated by amino-pyridine N-H?N hydrogen bonds feature in the crystal packing; these are connected into a three-dimensional architecture by C-H?? inter-actions and Cl?Cl contacts [Cl?Cl = 3.3896?(14)?Å].
