2-Iodo-1,3-dimethoxybenzene

Abstract

Crystals of the title compound, C8H9IO2, were obtained from a dimethyl sulfoxide solution of 2,6-dimethoxybenzoic acid and iodobenzene diacetate under a nitrogen atmosphere at 353 K. In the crystal structure, molecules are linked by weak C—H...π interactions, generating interpenetrating one-dimensional chains of perpendicularly oriented molecules extending along [011] and [0overline{1}1]. Chains are also formed through non-bonding C—I...π contacts extending in the same directions, projecting a zigzag motif in view down [100]. The I...Cg distance is 3.695 (2) Å and the C—I...Cg angle is 164.17 (14)°. The molecular symmetry m coincides with the mirror plane of the space group Cmc21, resulting in a half-molecule in the asymmetric unit (Z′ = ½).
