The title compound, C15H14N2O3·H2O, consists of a benzodiazepinedione system fused to a pyrrole system. The seven-membered ring adopts a boat-shaped conformation (with the methine C atom as the prow); the five-membered ring adopts an enveloped-shaped conformation (with the hydroxy-bearing C atom as the flap). In the crystal, adjacent molecules are linked by O—H...O hydrogen bonds into sheets parallel to (102). In addition, Cacetylinic—H...O hydrogen bonds occur.
