The preparation of bromylfluoride BrO2F by several methods is described as well as its reaction with KF to give K[BrF2O2]. The Ramanspectrum of BrO2F has been interpreted in terms of a pyramidal structure. The preparation of bromosyl trifluoride BrOF3 by the reaction of K[BrF4O] with HF is described together with some of its properties. The 19F n.m.r. spectrum of molten BrOF3 and its solutions in
描述了通过几种方法制备溴化氟BrO 2 F以及其与KF的反应生成K [BrF 2 O 2 ]。BrO 2 F的拉曼光谱已经根据金字塔结构进行了解释。描述了通过K [BrF 4 O]与HF反应制备溴化三氟化溴BrOF 3及其一些性能。熔融BrOF 3的19 F nmr光谱及其在SO 2 ClF和SO 2 F 2中的溶液已经根据氟交换进行了记录和解释。拉曼光谱是根据在液体,固体和HF溶液中的缔合来解释的。BrF 5的水解和BrF 5与IO 2 F,IOF 3和I 2 O 5的反应生成BrO 2 F,但不生成BrOF 3,而BrF 5与IO 2 F 3的反应生成BrO 2的混合物F和BrOF 3。将化合物BrO 2 F氟化为BrOF 3,然后通过KrF氟化为BrF 52,但没有形成溴( VII)物种。

The novel hypervalent, highly coordinated, high-oxidation state anions IF6Oâ, TeF6O2â, TeF7â, IF8â and TeF82â have been synthesized in anhydrous MeCN using anhydrous N(Me)4+Fâ as the fluoride ion source; the anions have been characterized by NMR and vibrational spectroscopy and represent novel examples of seven and eight-coordinate species having symmetries C5v(IF6Oâ, TeF6O2â), D5h, (TeF7â) and D4d(IF8â, TeF82â).
