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

ABSTRACT: 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.
