1,3-Bis(2,6-diisopropyl­phen­yl)-4,5-dihydro-1H-imidazol-3-ium triiodide

In the crystal structure of the title compound, C(27)H(39)N(2) (+)·I(3) (-), the imidazolidinium ring is perpendicular to a mirror plane which bis-ects the cation. The dihedral angle between the imidazolidinium ring and the benzene ring is 89.0 (2)°. The triiodide anion also lies on a mirror plane and is almost linear with an I-I-I bond angle of 178.309 (18)°.

8-Iodo­quinolinium triiodide tetra­hydro­furan solvate

The title compound, C(9)H(7)IN(+)·I(3) (-)·C(4)H(8)O, was synthesized from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium cation is essentially planar and the triiodide ion is almost linear. N-H⋯O hydrogen bonds, and inter-molecular I⋯I [3.7100 (5) Å] and I⋯H inter-actions, between the cation, anion and solvent mol-ecules result in the formation of sheets oriented parall...

Two New Polyiodides in the 4,4′-Bipyridinium Diiodide/Iodine System

The reaction of bipyridine with hydroiodic acid in the presence of iodine gave two new polyiodide-containing salts best described as 4,4′-bipyridinium bis(triiodide), C10H10N2[I3]2, 1, and bis(4,4′-bipyridinium) diiodide bis(triiodide) tris(diiodine) solvate dihydrate, (C10H10N2)2I2[I3]2 · 3 I2 · 2H2O, 2. Both compounds have been structurally characterized by crystallographic and spectroscopic ...
