title: Towards Polysulfuric Acids: The Hydrogentrisulfate Anion [HS3O10]-in A[HS3O10] (A=Na, K, Rb).
abstract: The reaction of Na2SO4and K2SO4with fuming sulfuric acid (65 % SO3) yielded colorless extremely sensitive crystals of Na[HS3O10] (monoclinic; P21/n (No. 14); Z=4; a=707.36(2), b=1378.56(4), c=848.10(3) pm; β=94.817(1)°; V=824.09(4)⋅106pm3) and K[HS3O10] (orthorhombic; Pccn (No. 56); Z=4; a=1057.16(3), b=807.81(2), c=897.57(2) pm; V=766.51(3)⋅106pm3). The analogous rubidium compound Rb[HS3O10] (orthorhombic; Pnma (No. 62); Z=4; a=891.43(3), b=1095.34(4), c=839.37(3) pm; V=819.58(5)⋅106pm3) originates from the reaction of Rb2CO3and SO3. All of the different structures contain the hitherto unknown anion [HS3O10]-and are stamped by strong hydrogen bonds linking the anions either to dimers or chains. Theoretical investigations by DFT methods give further insight in the structural characteristics of [HS3O10]-. The preparation of the [HS3O10]-anion can be seen as an important milestone on our way to the still elusive polysulfuric acids.
