Abstract:
In the title compound, C16H13IO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.015 (2) Å] and the 4-methyl-phenyl ring is 70.35 (5)°. In the crystal, mol-ecules are linked by pairs of π-π inter-actions between the furan and benzene rings, with centroid-centroid distances of 3.667 (3) and 3.701 (3) Å. The mol-ecules stack along the a-axis direction. In addition, pairs of C-H⋯O hydrogen bonds between inversion-related dimers [which generate R 2 (2)(10) loops] and a short I⋯I [3.7534 (3) Å] contact are observed.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
