m-Xylylenediaminium sulfate: crystal structure and Hirshfeld surface analysis

Abstract

The crystal structure of the title salt {systematic name: [1,3-phenylenebis(methylene)]bis(azanium) sulfate}, C8H14N22+·SO42−, consists of infinite (100) sheets of alternating organic and inorganic entities The m-xylylenediaminium cations are linked to the sulfate anions by N—H...O and asymmetric bifurcated N—H...(O,O) hydrogen bonds, generating a three-dimensional network. A weak C—H...O interaction also occurs. The Hirshfeld surface analysis and the two-dimensional fingerprint maps indicate that the packing is dominated by H...O/O...H and H...H contacts.
