TeF 5 OCl与碳氟碘化物CF 3 I,C 2 F 5 I,nC 3 F 7 I和iC 3 F 7 I的低温反应导致形成R f I(OTeF 5)2加合物。除三氟甲基衍生物外,它们均为稳定的无色化合物。三氟甲基加合物在-78°C以上分解,得到以前未知的CF 3 OTeF 5。全氟乙基和正丙基加合物在120°C或在紫外线辐射下分解,得到C 2 F 5 OTeF 5和n C 3 F 7 OTeF 5。这些反应构成了主要的R f OTef 5化合物的新合成。尝试将该合成扩大到仲碳氟碘化物是失败的。

(CH(3))(3)Sn(O=S(CH(3))(2))(2)(+) cation and the OTeF(5)(-) anion are formed. (CH(3))(3)SnOTeF(5) and (CH(3))(3)SnN(SO(2)CF(3))(2) react differently with water. While the Te-F bonds in the OTeF(5) group of (CH(3))(3)SnOTeF(5) undergo complete hydrolysis that results in the formation of [(CH(3))(3)Sn(H(2)O)(2)](2)SiF(6), (CH(3))(3)SnN(SO(2)CF(3))(2) forms the stable hydrate salt [(CH(3))(3)Sn(H(2)O)

The homoleptic [Ni(OTeF5)4]2−anion has been selectively prepared and arises as an analogue of [NiF4]2−, but featuring the discrete tetrahedral geometry of the heavier halonickelates. This high-spin complex has enabled the investigation of the electronic properties of the [OTeF5]− group in coordinationchemistry, showing that it behaves as the fluoride also in ligand-field terms.

A synthetic route to the gold(III) pentafluoroorthotellurates [Au(OTeF5)3] and [Au(OTeF5)4]− based on commercially available gold chlorides is presented. The former was classified as a Lewissuperacid, with an enhanced Lewis acidity yet better manageability compared to AuF3, underlining the potential of the −OTeF5 group to also stabilize highly reactive transition-metal compounds.

NEVPT2) study, the properties and electronic structure of this species have been investigated. It exhibits a distorted tetrahedral structure around the cobalt center and can be described as a d7 system with a quartet (S = 3/2) groundstate. A comparative bonding analysis of the (pseudo)tetrahedral [CoX4]2– anions (X = OTeF5, F, Cl) revealed that the strength of the Co–X interaction is similar in the

Compounds containing Mn–O bonds are of utmost importance in biological systems and catalytic processes. Nevertheless, mononuclear manganese complexescontaining all O-donor ligands are still rare. Taking advantage of the low tendency of the pentafluoroorthotellurate ligand (teflate, OTeF5) to bridge metal centers, we have synthesized two homoleptic manganese complexes with monomeric structures and
