Diisopropylammonium methanesulfonate

G. J. Reiss and M. K. Meyer

Abstract: The title molecular salt, C₆H₁₆N⁺·CH₃SO₃^-, has been determined at 150 K. Two diisopropylammonium cations (dipH) and two anions form N-HO hydrogen-bonded cyclic dimers lying around centers of symmetry. Only two of the three O atoms of the methanesulfonate anion are involved in hydrogen bonding, resulting in slightly longer S-O bond lengths. The title structure represents an example of a sulfonate anion that is part of a hydrogen-bonding R₄⁴(12) graph-set motif, which is well known for related dipH acetates. Additionally, the Raman and the IR spectroscopic data for the title compound are presented.
