title: (-)-Argemonine hemihydrate.
abstract: (-)-Argemonine hemihydrate [systematic name: (6S,12S)-2,3,8,9-tetramethoxy-13-methyl-13-azadibenzo[b,f]bicyclo[3.3.1]nona-2,6-diene hemihydrate], C21H25NO4.0.5H2O, is a tertiary pavinane alkaloid. Both partially saturated nitrogen heterocycles adopt twisted half-chair conformations. The angle between the two aromatic rings is 86.90 (5) degrees.
