(2008). Acta Cryst. E64, o366]. Two independent formula units comprise the asymmetric unit with the major difference in their mol-ecular structures relating to the relative dispositions of the cyclohexyl rings [dihedral angles = 79.88 (6) and 67.72 (5)°]. Further, the independent anions form distinctive patterns of hydrogen-bonding interactions, i.e. 2 × N - H⋯N versus N - H⋯N and N - H⋯S. The resulting supra-molecular architecture is a supra-molecular chain along the c axis based on a square-wave topology. © Selvakumaran et al. 2011.enArticle
