(E)-1-(4-Amino-phen-yl)-3-(pyridin-3-yl)prop-2-en-1-one.

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)†à 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)†à is also observed.
