X.-J. Cao, C.-R. Sun and Y.-J. Pan

Abstract: The flunixin-meglumine complex [(2S,3R,4R,5R)-2,3,4,5,6-pentahydroxy-N-methyl-1-hexanaminium 2-[2-methyl-3-(trifluoromethyl)anilino]nicotinate], C₇H₁₈NO₅⁺·C₁₄H₁₀F₃N₂O₂^-, is a non-steroidal anti-inflammatory drug (NSAID) and a non-narcotic analgesic drug with antipyretic activities. In its crystal structure, the meglumine cations are linked through O-HO and N-HO hydrogen bonds to form layers parallel to the ab plane. The flunixin anions are arranged between the two cationic layers and are linked to the cations through O-HO hydrogen bonds.
