“…The white solid product was dried in vacuum for 24 h a t 150°C. The infrared spectrum correlates well with a superposition of the spectra of a-iron(I1) methanesulfonate and methanesulfonic acid (8 Bismethanesulfonates of Calcium, Cobalt, Copper, and Zinc, M(CH3SOJ2 Co(CH3S03), and CU(CH,SO,)~ were prepared as described previously (3). The other compounds were prepared by the reaction of silver (1) Infrared and electronic spectra were obtained as before (3).…”

The iron(II) sulfonates Fe(CF3SO3)2 and Fe(p-CH3C6H4SO3)2 have been prepared and on the basis of vibrational and electronic spectra and magnetic and MÖssbauer data have been assigned a layer lattice structure involving hexacoordinated iron(II) and terdentate bridging anions. The FeO6 chromophore in these compounds is distorted by a trigonal elongation along the C3 axis. Fe(CH3SO3)2 has been obtained in two isomeric forms, one having a trigonal elongation of the FeO6 chromophore, the other a trigonal compression. No structural isomerism has been found for the other iron(II) sulfonates; however, evidence for such isomerism in methanesulfonates of cobalt(II) and zinc(II) is presented. While Fe(CF3SO3)2 and Fe(p-CH3C6H4SO3)2 appear to be magnetically dilute the presence of antiferromagnetic coupling in both forms of Fe(CH3SO3)2 is indicated. The iron(III) sulfonates, Fe(CF3SO3)3, Fe(p-CH3C6H4SO3)3, and Fe(CH3SO3)3, have been prepared and all three are magnetically concentrated exhibiting magnetic moments which are significantly less than 5.92 BM and which decrease with decreasing temperature.

“…It is generally accepted that fluorosulfuric acid undergoes an autoprotolysis during the formation of [SO 3 F] À anions and [H 2 SO 3 F] + cations with a concentration of 3.5 10 À4 mol L À1 of each ion. [11] The spectroscopic and structural properties of the pure acid and the [SO 3 F] À anion are well known, [13][14][15][16][17][18] but the existence of [H 2 SO 3 F] + is only assumed on the basis of cryoscopic and conductivity measurements. [11] 1 H and 19 F NMR spectroscopy experiments in superacidic solutions of the magic acid HSO 3 F/SbF 5 have been performed.…”

Sulfurtrioxide reacts with the superacidic solutions XF/SbF(5) (X=H, D) to form the corresponding salts [X(2)SO(3)F](+)[SbF(6)](-), which are the protonated forms of fluorosulfuric acid. The salts have been characterized by vibrational spectroscopy and a single-crystal structure analysis. [H(2)SO(3)F](+)[SbF(6)](-) crystallizes in the monoclinic space group P2(1)/n (no. 14) with four formula units in the unit cell. The crystal structure possesses a distorted tetrahedral O(3)SF skeleton of the cations, which are linked with two strong hydrogen bridges to [SbF(6)](-) anions and forms a one-dimensional chain. The crystal structure and the vibrational spectra are compared to the quantum-chemical-calculated free [H(2)SO(3)F](+) cation. Additionally, an [H(2)SO(3)F(HF)(2)](+) unit was calculated at the RHF/6-311(++)G(d,p) level to simulate HF hydrogen bridges found in the solid state.
