## Abstract

Comparison of conformational features on halogen substitution in 1, 2-diaryl-6-methoxy-1, 2, 3, 4-tetrahydroisoquinolines based on crystal structures indicate that the derivatives with fluorine differ significantly from those of chlorine and bromine. The packing of the molecules in the lattice are nearly identical for derivatives of chlorine and bromine while the fluorine derivatives display C-F...F, C-H...F and $C-F...\pi$ interactions.
