- THE SYNTHESIS AND CRYSTAL STRUCTURE OF PERFLUOROTELLURANTHRENE, C12F8Te2
-
The reaction of tetrafluoro-1,2-diiodobenzene with tellurium yields an oil which, on treatment with bromine yields perfluorotelluranthrene-9,9,10,10-tetrabromide.The latter is reduced by sodium sulfide to perfluorotelluranthrene.The crystal structure of perfluorotelluranthrene is reported.

- THE STRUCTURE OF A TRICLINIC FORM OF OCTAFLUOROSELENANTHRENE, (C6F4)2Se2
-
Octafluoroselenthrene exists in two different crystal forms, monoclinic and triclinic.It is shown here that the molecular structure in the triclinic modification is very similar to that found previously in monoclinic crystals.

To clear some confusion in the literature, the "direct syntheses" of As2(C6F4)3 and of Sb2(C6F4)3 have been repeated and the identities of the compounds confirmed by analytical data and spectroscopic methods.Mixtures of As and Sb, when heated with 1,2-I2C6F4, give As2(C6F4)3, Sb2(C6F4)3 and AsSb(C6F4)3.When Sb is heated with 1,2-I2C6H4 and 1,2-I2C6F4, three compounds are formed: Sb2(C6F4)3, Sb2(C6F4)2(C6H4) and Sb(C6F4)(C6H4)2.

When heated with Group V and Group VI elements, the phenylenemercurials (C6H4Hg)3, (C6F4Hg)3 and (C6Cl4Hg)3 form heterocycles of formulae M2(C6X4)3 and M'2(C6X4)2 where M = As, Sb, Bi and M' = S, Se, Te.The compounds Te2(C6Cl4)2 and M2(C6Cl4)3 (M = As, Sb, Bi) were also obtained by heating the elements with 1,2-I2C6Cl4, which was prepared by mercuration of 1,2-H2C6Cl4 followed by iododemercuration.Octachlorothianthrene has been obtained by heating sulphur with Te2(C6Cl4)2, C6Cl6 or C6H5I, and from the reaction between 1,2-H2C6Cl4, AlCl3, and S2Cl2.
