Abstract
Three new crystal structures of dihydroergopeptines: dihydro-α-ergokryptine mesylate monohydrate acetone solvate (1), dihydro-α-ergokryptine mesylate monohydrate nitromethane solvate (2), and dihydroergocornine mesylate monohydrate methanol solvate (3) have been determined by X-ray single crystal diffraction. These structures were compared with published structures of dihydro-α-ergokryptine mesylate monohydrate ethanol solvate (4), dihydro-β-ergokryptine mesylate monohydrate methanol solvate (5), and dihydroergocristine mesylate monohydrate (6).
