Dicyclohexylammonium thiocyanate: monoclinic polymorph
The title salt, C(12)H(24)N(+)·NCS(−), represents a monoclinic polymorph of the previously reported orthorhombic form [Khawar Rauf et al. (2008 ▶). Acta Cryst. E64, o366]. Two independent formula units comprise the asymmetric unit with the major difference in their molecular structures relating t...

description | The title salt, C(12)H(24)N(+)·NCS(−), represents a monoclinic polymorph of the previously reported orthorhombic form [Khawar Rauf et al. (2008 ▶). Acta Cryst. E64, o366]. Two independent formula units comprise the asymmetric unit with the major difference in their molecular 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 supramolecular architecture is a supramolecular chain along the c axis based on a square-wave topology. |
