Crystal structure of 1-(1-chloro-eth-yl)-6,7-dimeth-oxy-1,2,3,4-tetra-hydro-isoquinolinium chloride.

1-(1-Chloro-eth-yl)-6,7-dimeth-oxy-1,2,3,4-tetra-hydro-iso-quinoline was synthesized through the reaction of homoveratryl-amine with racemic lactic acid. The formation of two enanti-omers, and , was detected by performing X-ray diffraction analysis on their chloride salts. The asymmetric unit of the crystal consists of a CHClNO mol-ecular cation and a Cl anion.

Crystal structure of 2,3-dimeth-oxy-5,6,7,8,13,13a-hexa-hydro-6a,8-di-aza-indeno-[2,1-b]phenanthrene methanol monosolvate.

The asymmetric unit of the title solvate, C21H22N2O2·CH3OH, contains one methanol solvent mol-ecule and one mol-ecule of the heterocycle that is built up by the fusion of four six-membered rings A, C, D, E and one five-membered ring B. The indole moiety (rings A and B) is essentially planar, with an r.m.

[2-(3,4-Di-meth-oxy-phen-yl)eth-yl](3-{N-[2-(3,4-di-meth-oxy-phen-yl)eth-yl]carbamo-yl}prop-yl)aza-nium chloride dihydrate.

The asymmetric unit of the title hydrated salt, C24H35N2O5 (+)·Cl(-)·2H2O, contains one organic cation that has its protonation site at the amine function, one chloride anion and two lattice water mol-ecules. In the crystal, one pair of lattice water mol-ecules and two chloride anions form a four-membered centrosymmetric hydrogen-bond cycle. In addition, O-H⋯O, N-H⋯O and N-H⋯Cl hydrogen bonds involving the N-H groups, the water mol-ecules and the C=O group are observed.
