چکیده
In the crystal structure of the title compound, C(14)H(11)NO(3), isolated from the reaction of 2-bromo-1-phenyl-ethanone and pyridine-4-carboxylic acid using triethyl-amine as a base to deprotonate the organic acid, the mol-ecular packing is stabilized by C-H⋯π inter-actions involving the phenyl and pyridine rings. The C-C-O-C torsion angle for the linkage between the two carbonyl groups is -80.8 (2)°, and the planes of the phenyl and pyridyl rings form a dihedral angle of 65.8 (1)°.

In the title compound, C(27)H(25)NO(4), the tetra-hydro-pyridine ring adopts a half-chair conformation. The three phenyl rings form dihedral angles of 66.33 (7), 87.36 (8) and 36.90 (7)° with the least-squares plane through the tetra-hydro-pyridine ring. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond, generating an S(6) motif.

متن کاملHexane-1,6-diammonium bis(pyridine-2-carboxylate)
The title compound, C(6)H(18)N(2) (2+)·2C(6)H(4)NO(2) (-), consists of a doubly protonated hexa-methyl-enediammonium dication and two pyridine-2-carboxyl-ate anions. These ions inter-act by means of inter-molecular N-H⋯O and N-H⋯N hydrogen bonds to form a two-dimensional array. The carboxyl-ate groups of the anions appear to be delocalized on the basis of the C-O bond lengths.
