Synthesis and crystal structure of ((E)-{2-[(E)-(4-hy-droxynaphthalen-1-yl)methyl-idene]hydrazin-1-yl}(methyl-sulfan-yl)methyl-idene)azanium hydrogen sulfate monohydrate.

ABSTRACT: In the title hydrated mol-ecular salt, C₁₃H₁₄N₃S⁺·HSO₄^-·H₂O, the protonation of the azomethine N atom in sulfuric acid medium involves the formation of the bis-ulfate anion. The mol-ecular structure of the cation is obtained from the thiol tautomer of thio-semicarbazone wherein the naphthalene moiety and the conjugation of the bonds contribute to the planarity of the mol-ecular skeleton. In the crystal, the cation, anion and water mol-ecule of crystallization are linked by a series of O-H⋯O and N-H⋯O hydrogen bonds, forming a three-dimensional network. Within this network, there are also C-H⋯π inter-actions present involving symmetry-related naphthalene rings.
