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.
