The formation of the complete series of phenylazophenyl(C,N′(tellurium(II) halides (fluoride, chloride, bromide and iodide) is described in this paper. The monoiodide arose from the reaction of the monobromide and diiodine. The new monoclinic modification of phenylazophenyl(C, N′)tellurium(II) chloride (RTeCl) contains only one independent molecule in the unit cell, whereas a previously reported modification
本文描述了完整系列的苯基偶氮苯基(C,N '(卤化碲(II))(氟化物,氯化物,溴化物和碘化物)的形成。苯基偶氮苯基(C,N')氯化碲(II)(RTeCl)在晶胞中仅包含一个独立分子,而先前报道的修饰每晶胞中包含两个分子,并且是三斜晶的。键长TeN(2)处于二次键合相互作用的预期范围内,即2.210(7)–2.252(8)Å。在比较一系列化合物的TeN(2)键长时,应注意到随着Te原子上的负电性原子越多,次级相互作用越强。通过两种独立的方法合成的一氟化物是一种橙色液体,其特征在于125 Te和19 F NMR。
