2019年10月17日 · Bromine fluoride dioxide (bromyl fluoride) has long been known, 1 and its pyramidal structure has been established by spectroscopic methods. 2 It is a very reactive and unstable species that decomposes above 10 °C, often with explosion.

2007年5月11日 · The molecular structures and the neutral–anion energy separations of the BrO n F/BrO n F − ( n = 2, 3) species have been investigated using four density functional theory (DFT) methods. The FBrOO and FBrOOO chain structures are found to be the global minima for BrO n F/BrO n F − ( n = 2, 3) species.

2019年12月12日 · BrO 2 F and (CH 3) 3 Si‐OSO 2 CF 3 in SO 2 ClF also react to Br 3 O 6 + SO 3 CF 3 −, now in the form of a yellow fine powder, as confirmed by its identical Raman spectrum (see the Supporting Information). In speculations about the formation of these mixed‐valent cations, the intermediacy of the free radical . BrO 2 could be considered.

2024年8月3日 · Reactions of Bromine Fluoride Dioxide, BrO2F, for the Generation of the Mixed‐Valent Bromine Oxygen Cations Br3O4+ and Br3O6+ 二氟化溴BrO2F生成混合价溴氧阳离子Br3O4+和Br3O6+的反应

2019年11月13日 · A new synthesis for BrO2F is described: A solid co-condensate of BrF5 and H2O (molar ratio 5:1), prepared at − 196°C, reacts to BrO2F by warming up to −60°C. The nearly quantitative conversion of H2O …

O₂BrF is Ammonia-derived structured and crystallizes in the monoclinic Cc space group. The structure is zero-dimensional and consists of four O₂BrF clusters. There are two inequivalent O²⁻ sites. In the first O²⁻ site, O²⁻ is bonded in a single-bond geometry to one Br⁵⁺ atom. The O-Br bond length is 1.62 Å. In the second O²⁻ site, O²⁻ is bonded in a single-bond geometry ...

2009年5月19日 · Five hybrid Hartree–Fock/density functional theory (DFT) and pure DFT methods with DZP++ basis sets were used for predictions of the structures and energetics of molecules and anions, and the neutral-anion energy separations in the series (n = 2 and 3).

2019年10月17日 · The Raman spectra of solid and liquid BrO2F have been obtained and show that in both states BrO2F is monomeric with a pyramidal structure, like ClO2F but differing from polymeric IO2F.

This work is the first on the subject since 1963 when BrO2F was the only known oxyfluoride of bromine. Since then a number of other oxyfluoro compounds have been prepared, and a considerable amount of information on the structure and properties of all these compounds including additional information on BrO2F has been obtained.

O2BrF is Ammonia-derived structured and crystallizes in the monoclinic Cc space group. The structure is zero-dimensional and consists of four O2BrF clusters. there are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Br5+ atom. The O–Br bond length is 1.63 Å.
