Abstract
The compounds 1-(2-fluorophenyl)-6,7-dimethoxy-2-phenyl-1,2,3,4-tetrahydroisoquinoline (1) and 5-(2-fluorophenyl)-6-phenyl-5,6,7,8-tetrahydro dioxolo[4,5-g]isoquinoline (2) have been studied via single crystal X-ray diffraction at 100.0(2) K. Compound 1 crystallizes in the space group P̅1 with two molecules in the asymmetric unit (Z=4), whereas compound 2 crystallizes in the space group P21/n. The two molecules of 1 in the asymmetric unit offer different modes of interactions via C-H...F and C-H...O resulting in altered molecular conformations. Compound 2 essentially packs via C-H...F interaction.
