In the title compound [systematic name: (4R,4aS,7aR,12bS)-3-cyclopropylmethyl-4a,9-hydroxy-7-oxo-2,3,4,4a,5,6,7,7a-octahydro-1H-4,12-methanobenzofuro[3,2-e]isoquinolin-3-ium bromide methanol monosolvate], C21H26NO4+·Br−·CH3OH, two of the three six-membered rings adopt chair conformations while the third, which contains a C=C double bond, adopts an approximate half-boat conformation. The 2,3-dihydrofuran ring adopts an envelope conformation. In the crystal, the components are linked by O—HO and O—HBr hydrogen bonds. The absolute stereochemistry was inferred from one of the starting materials.

In the title compound, [Cu(C7H7N2O)(C7H8N2O)(H2O)]ClO4·H2O, the CuII ion is five-coordinated by the N atoms from the 1-(pyridin-2-yl)ethanone oximate and 1-(pyridin-2-yl)ethanone oxime ligands and by the water O atom in a distorted square-pyramidal geometry. The two organic ligands are linked by an intramolecular O—HO hydrogen bond. In the crystal, molecules and ions are linked by O—HO hydrogen-bonding interactions, forming chains along the a axis. The perchlorate O atoms are disordered in a 0.58 (2):0.42 (2) ratio.

The title compound, C12H14N2O, was obtained by reaction of (±)-1-(1H-benzimidazol-2-yl)ethanol with 3-bromoprop-1-ene. The asymmetric unit contains four crystallographically independent molecules. In the crystal, molecules 1 and 2 are linked via O—HN hydrogen bonds, forming chains propagating along [010]. Molecules 3 and 4 are linked to these chains via O—HO hydrogen bonds.
