title: (-)-Norfluoro-curarine ethanol monosolvate.
abstract: The title compound, C19H20N2O·C2H5OH, is an ethanol solvate of an indol alkaloid which was extracted from the plant Vinca erecta. The fused piperidine ring adopts an approximate boat conformation and the pyrrolidine ring an envelope conformation with one of the methyl-ene C atoms at the flap. An intra-molecular N-H⋯O hydrogen bond forms an S6 ring motif. In the crystal, norfulorocurarine and ethanol mol-ecules are linked into a chain along the c-axis direction through N-H⋯O and O-H⋯N hydrogen bonds.
