Abstract
The crystal structure of the tetra-ethyl-ammonium salt of the non-steroidal anti-inflammatory drug nimesulide (polymorph II) (systematic name: tetra-ethyl-ammonium N-methane-sulfonyl-4-nitro-2-phen-oxy-anilinide), C8H20N+·C13H11N2O5S-, was determined using single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic space group P21/c with one tetra-ethyl-ammonium cation and one nimesulide anion in the asymmetric unit. In the crystal, the ions are linked by C-H⋯N and C-H⋯O hydrogen bonds and C-H⋯π inter-actions. There are differences in the geometry of both the nimesulide anion and the tetra-ethyl-ammonium cation in polymorphs I [Rybczyńska & Sikorski (2023 ▸). Sci. Rep. 13, 17268] and II of the title compound.
