(3E)-4-[(Naphthalen-1-yl)amino]­pent-3-en-2-one hemihydrate

ABSTRACT: In the title compound, the dihedral angle between the naphthalene ring system and the amino­pentenone fragment mean plane (C=C—N—C=O) is 76.91 (19)°. In the crystal, a water mol­ecules are connected with the N-naphthyl­pent-3-en-2-one mol­ecules by O—H⋯O-type hydrogen bonds. The title compound, C15H15NO·0.5H2O, was prepared from α-naphthyl­amine and 2,4-penta­nedione in a 1:1 ratio. An intra­molecular N—H⋯O hydrogen bond in the N-naphthyl­pent-3-en-2-one mol­ecule involving the amine and carbonyl groups strengthens the structure. The water mol­ecule interacts with two symmetry-related N-naphthyl­pent-3-en-2-one mol­ecules viaby O—H⋯O hydrogen bonds.
