m-Xylylenediaminium sulfate: crystal structure and Hirshfeld surface analysis

The crystal structure of the title salt {systematic name: [1,3-phenyl­enebis(methyl­ene)]bis­(aza­nium) sulfate}, C(8)H(14)N(2) (2+)·SO(4) (2−), 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.
