The structures of three 5-H-indeno[1,2-c]pyridazin-5-one derivatives, potent type-B monoamine oxidase inhibitors, were investigated. The crystal structures were found to be stabilized by weak C-H⋯O hydrogen bonds. The packing was dominated by π-π stacking interactions between the heterocyclic central moieties of centrosymmetrically related molecules. The π-π stacking network led to a parallel arrangement along the a axis.
