Abstract

The title compound, C(7)H(8)INO, which crystallizes with three independent mol-ecules in the asymmetric unit, was prepared by the reaction of 3-meth-oxy-6-methyl-pyridine with KI and I(2) in tetra-hydro-furan solution. In the crystal structure, the three independent mol-ecules are arranged in a similar orientation with the three polar meth-oxy groups aligned on one side and the three non-polar methyl groups on the other side. The three mol-ecules, excluding methyl H atoms, are essentially planar, with r.m.s. deviations of 0.0141 (1), 0.0081 (1) and 0.0066 (2)Å. The three pyridine rings make dihedral angles of 58.09 (3) 66.64 (4) and 71.5 (3)°. The crystal structure features rather weak inter-molecular C-H⋯O hydrogen bonds, which link two mol-ecules into dimers, and short I⋯N contacts [4.046 (3) Å].
