Abstract
3-Acetyl-1,6,7,12b-tetrahydroindolo[2,3-a]quinolizin-2(12H)-one, C17H16N2O2, consists of two symmetry-independent molecules and each forms a layered structure stabilized by N-H…O and C-H…O hydrogen bonds. In 3-acetyl-6,7-dihydroindolo[2,3-α ]quinolizin-4(12H)-one monohydrate, C17H14N2O2·H2O, the structure is stabilized by O-H…O, N-H···O and C-H…O hydrogen bonds, with the ordered water molecule playing a crucial role in the self-assembly. Contribution from the weak interactions to the strong hydrogen-bonded network is a common feature in both structures.
