Dicyclo-hexyl-ammonium thio-cyanate: monoclinic polymorph.
The title salt, C(12)H(24)N(+)·NCS(-), represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Khawar Rauf et al. (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 cyclo-hexyl rings [dihedral angles = 79.88 (6) and 67.72 (5)°]. Further, the independent anions form distinctive patterns of hydrogen-bonding inter-actions, 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.
