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}, C8H14N2 2+·SO4 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.
