(−)-Norfluoro­curarine ethanol monosolvate

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 methyl­ene C atoms at the flap. An intra­molecular N—H...O hydrogen bond forms an S6 ring motif. In the crystal, norfulorocurarine and ethanol mol­ecules are linked into a chain along the c-axis direction through N—H...O and O—H...N hydrogen bonds.

1,2-Ethyl­enediaminium bis­(2-benzamido­benzoate)

In the title salt, C₂H₁₀N₂²⁺·2C₁₄H₁₀NO₃⁻, the ethyl­ene­diaminium dication lies on an inversion centre. In the anion, the benzene rings make a dihedral angle of 33.87 (9)° and intramolecular N—H...O and C—H...O hydrogen bonds occur. All the amino H atoms are involved in N—H...O hydrogen bonds. These hydrogen bonds link the ionic units into a three-dimensional network. In addition, the crystal structure also features weak C—H...O inter­actions.
