چکیده
The title chalcone derivative, C(14)H(12)N(2)O, consists of 4-amino-phenyl and pyridine rings bridged by a prop-2-en-1-one unit and exists in a trans configuration with respect to the C=C double bond. The mol-ecule is slightly twisted with a dihedral angle of 29.38 (7)° between the benzene and pyridine rings. The prop-2-en-1-one bridge is nearly planar with an r.m.s. deviation of 0.0384 (1) Å and makes dihedral angles of 15.40 (9) and 16.30 (9)°, respectively, with the benzene and pyridine rings. In the crystal, mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds into a layer parallel to the ab plane. A π-π inter-action with a centroid-centroid distance of 3.6946 (10) Å is also observed.

The mean planes of the benzene and pyridine rings in the title compound, C(15)H(12)BrNO(2), are nearly coplanar, subtending an angle of 2.8 (8)°. The prop-2-en-1-one group is also in the plane of these rings with an N-C-C-O torsion angle of 179.6 (3)°. A weak C-H⋯Br inter-molecular inter-action contributes to the crystal packing, creating a chain-like structure along the a axis.

The title compound, C13H10N2O2 [also called 1-(pyridin-2-yl)-3-(pyridin-3-yl)propane-1,3-dione], features an almost planar (r.m.s. deviation = 0.0095 Å) central C3O2 core consolidated by an intra-molecular hy-droxy-O-H⋯O(carbon-yl) hydrogen bond. Twists are evident in the mol-ecule, as seen in the dihedral angles between the central core and the 2- and pyridin-3-yl rings of 8.91 (7) and 15.88 (...

The title compound, C(15)H(13)NO, has two crystallographically independent mol-ecules in the asymmetric unit which differ principally in the periplanar angle formed by the benzene and pyridine rings [41.41 (3) and 17.92 (5)°]. The mol-ecules exhibit an E conformation between the keto group with respect to the olefin double bond.
