Diiododurene: four centrosymmetric molecules in general positions was written by Britton, Doyle;Gleason, William B.. And the article was included in Acta Crystallographica, Section C: Crystal Structure Communications in 2003.Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene This article mentions the following:
Diiododurene (1,4-diodo-2,3,5,6-tetramethylbenzene), C10H12I2, packs with four mols. in the asym. unit. All four of these mols. violate Kitaigorodsky’s suggestion that mols. with centers of symmetry will lie on crystallog. centers of symmetry. There is 5.6% disorder at one of the sites. Most of the I atoms are in contact with other I atoms, but only six of the I···I contacts are shorter than 4.2 Å. Of these six contacts, one set of three contacts forms a triangular set in which all of the I···I distances are <3.9 Å. Crystallog. data are given. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene).
1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene
