Dihydronium 3-nitrobenzenesulfonate

C. George, J. R. Deschamps and A. P. Purdy

Abstract: The title compound, H₅O₂⁺·C₆H₄NO₅S^-, crystallized slowly over a period of several years. It is stable and the dihydronium cation is well determined; all of the H-atom positions in the cation were refined. The strong hydrogen bond between the O atoms is nearly linear, with the H atom near the midpoint of the two O atoms. The refined O-H distances are 1.15  (2) and 1.27  (2)  Å, respectively.
