m-Xylylenediaminium sulfate: crystal structure and Hirshfeld surface analysis

International audienceThe crystal structure of the title salt \systematic name: [1,3-phenyl-enebis(methyl-ene)]bis-(aza-nium) 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(midline ellipsis)O and asymmetric bifurcated N-H(midline ellipsis)(O,O) hydrogen bonds, generating a three-dimensional network. A weak C-H(midline ellipsis)O inter-action also occurs. The Hirshfeld surface analysis and the two-dimensional fingerprint maps indicate that the packing is dominated by H(midline ellipsis)O/O(midline ellipsis)H and H(midline ellipsis)H contacts.[on SciFinder (R)
