The salts [AsX4][As(OTeF5)6] and [AsBr4][AsF(OTeF5)5] (X = Cl, Br) have been prepared by oxidation of AsX3 with XOTeF5 in the presence of the OTeF5 acceptors As(OTeF5)5 and AsF(OTeF5)4. The mixed salts [AsCl4][Sb(OTeF5)6-nCl(n-2)] and [AsCl4][Sb(OTeF5)6-nCl(n)] (n > or = 2) have also been prepared. The AsBr4+ cation has been fully structurally characterized for the first time in SO2ClF solution by
盐[AsX4] [As(OTeF5)6]和[AsBr4] [AsF(OTeF5)5](X = Cl,Br)是通过在OTeF5受体As(OTeF5)存在下用XOTeF5氧化AsX3制备的。 5和AsF(OTeF5)4。还制备了混合盐[AsCl4] [Sb(OTeF5)6-nCl(n-2)]和[AsCl4] [Sb(OTeF5)6-nCl(n)](n>或= 2)。通过[AsAsBr4] [AsF(OTeFs)5]的单晶X射线衍射研究,首次在SO2ClF溶液中通过75As NMR光谱对AsBr4 +阳离子进行了全面结构表征,并在固态下对AsBr4 +阳离子进行了结构表征。 9.778(4)A,b = 17.731(7)A,c = 18.870(8)A,alpha = 103.53(4)度,beta = 103.53(4)度,γ= 105.10(4)度,V = 2915( 2)在-183℃下,A3,Z
