Abstract
The title compound, C7H8INO, which crystallizes with three independent molecules in the asymmetric unit, was prepared by the reaction of 3-methoxy-6-methylpyridine with KI and I2 in tetrahydrofuran solution. In the crystal structure, the three independent molecules are arranged in a similar orientation with the three polar methoxy groups aligned on one side and the three non-polar methyl groups on the other side. The three molecules, 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 intermolecular C—H⋯O hydrogen bonds, which link two molecules into dimers, and short I⋯N contacts [4.046 (3) Å].
