title: A second monoclinic polymorph of N-cyclo-hexyl-N-ethyl-benzene-sulfonamide.
abstract: The crystal structure of the title compound, C(14)H(21)NO(2)S, is a polymorph of the structure reported by Khan et al. [Acta Cryst. (2009), E65, o2867] which is also monoclinic (space group P2(1)/c). The unit cell in the title structure is approximately half the volume of the previously reported polymorph and the asymmetric unit of the title compound contains one mol-ecule rather than two independent mol-ecules in the other polymorph. In the title mol-ecule, the cyclo-hexane ring is in the typical chair form. In the crystal structure, mol-ecules are linked via weak inter-molecular C-H⋯O inter-actions, forming a chain along the b-axis direction.
