| مستخلص: |
The crystal structure of the tetraethylammonium salt of the non-steroidal antiinflammatory drug nimesulide (polymorph II) (systematic name: tetraethylammonium N-methanesulfonyl-4-nitro-2-phenoxyanilinide), C8H20N+-C13H11N2O5S-, was determined using single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic space group P21/c with one tetra-ethylammonium 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 interactions. There are differences in the geometry of both the nimesulide anion and the tetraethylammonium cation in polymorphs I [Rybczyiiska & Sikorski (2023). Sci. Rep. 13, 17268] and II of the title compound.
