Ortho-rhom-bic polymorph of (6,7-dimeth-oxy-1,2,3,4-tetra-hydro-isoquinolin-1-yl)methanol.

Project description:The asymmetric unit of the title compound, C(12)H(17)NO(3), contains two mol-ecules with different conformations. It is a polymorph of the monoclinic form [El Antri et al. (2004 ?). Mol-ecules, 9, 650-657]; the samples were crystallized at different temperatures from the same solvent. In both structures, mol-ecules are linked by O-H?N hydrogen bonds, forming chains. The conformations of the chains and their packing differ markedly in the two polymorphs.

[(1R,3S)-6,7-Dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinolin-3-yl]methanol 2.33-hydrate.

Project description:The title compound, C(18)H(21)NO(3)·2.33H(2)O, is the fourth reported member in a series of (1R,3S)-6,7-dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinoline derivatives used in catalysis as ligands (or their precursors). The N-heterocycle in the structure adopts a half-chair conformation. The dihedral angle between the benzene rings is 77.29?(13)°. There are three ill-resolved water molecules of crystallization in the structure (one of them rotationally disordered about a threefold axis) involved in short contacts probably due to hydrogen bonding.

6,7-Dimeth-oxy-1,4-anthraquinone.

Project description:The mol-ecule of the title compound, C(16)H(12)O(4), is almost planar; the two meth-oxy groups are slightly out of the plane of the anthraquinone ring system, with C-C-O-C torsion angles of -6.25?(19) and -10.22?(19)°. In the crystal structure, the mol-ecules adopt a herringbone arrangement and form face-to-face slipped anti-parallel ?-? stacking inter-actions along the b axis, with an inter-planar distance of 3.278?(2)?Å.

6,7-Dimeth-oxy-2,4-di-phenyl-quinoline.

Project description:In the title structure of the title compound, C23H19NO2, two conformationally similar mol-ecules (A and B) comprise the asymmetric unit.

3,3'-Oxybi[isobenzofuran-1(3H)-one].

Project description:The title compound, C(16)H(10)O(5), consists of two isobenzofuran-1(3H)-one moieties which are linked by a bridging O atom.

Two chiral carbon centres are observed in the compound, but their absolute configurations could not be determined. In the crystal structure, inter-molecular C-H?O hydrogen bonds link mol-ecules into zigzag chains along c. Additional C-H?O inter-actions connect adjacent chains.
