Bis(adeninium) bis(hydrogensulfate) sulfate

Abstract

The title compound, 2C5H7N5 2+·2HSO4 -·SO4 2-, was synthesized from adenine and sulfuric acid. The asymmetric unit contains two diprotonated adeninium cations, two bisulfate anions and one sulfate anion. The crystal structure is stabilized by classical N-H⋯O and O-H⋯O hydrogen bonds, and weak C-H⋯O and C-H⋯N hydrogen bonds, generating a three-dimensional network.
