Crystal structure and Hirshfeld surface analysis of (2)-3-oxo--phenyl-2-[(1-pyrrol-2-yl)methylidene]butanamide monohydrate.

In the title compound, CHNO·HO, the 1-pyrrole ring makes a dihedral angle of 59.95 (13)° with the phenyl ring. In the crystal, the mol-ecules are connected by C-H⋯O hydrogen bonds into layers parallel to the (020) plane, while two mol-ecules are connected to the water mol-ecule by two N-H⋯O hydrogen bonds and one mol-ecule by an O-H⋯O hydrogen bond.
