Dicyclo-hexyl-ammonium thio-cyanate: monoclinic polymorph.

ABSTRACT: 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.
