Bis(diisopropylammonium) sulfate

G. J. Reiß and J. S. Engel

Abstract: Bis(diisopropylammonium) sulfate, 2C₆H₁₆N⁺·SO₄^2-, crystallizes in the monoclinic centrosymmetric space group P2₁/n. The asymmetric unit contains two crystallographically independent diisopropylammonium cations and one sulfate anion in general positions. Strong hydrogen bonding occurs between the cations and anions, forming layers parallel to ( $\overline 1$ 01). Each layer is composed of ring systems that can be classified according to Etter's nomenclature as R₄⁴(12) and R₁₂¹²(36). IR and Raman spectroscopy confirm the presence of a nearly undistorted sulfate anion.
