4-[N,N 3-Dihydro Monohydrate

Abstract

The title compound, C<inf>27</inf>H<inf>27</inf>N<inf>5</inf>O <inf>3</inf>·H<inf>2</inf>O, is built up from pyrazolinone, phenyl and acetophenone oxime moieties. The 2-phenyl substituent is nearly perpendicular to the pyrazolinone ring, with a dihedral angle of 87.66 (1)°. The acetophenone oxime moieties are twisted out of the pyrazolinonering plane by 47.04 (1)°. The molecules in the crystal pack in an antiparallel fashion and are held together by hydrogen-bonded water molecules and intermolecular O-H⋯O and O-H⋯N hydrogen bonds.
