Anti-Inflammatory Drugs. V. [Tris-(2-hydroxymethyl)methyl]ammonium 2-[(2,6-Dichlorophenyl)amino]phenylacetate (TRISH. D)

The structure of the title compound, C₄H₁₂₂NO₃⁺.C₁₄₁₀Cl₂^-, in the solid-state consists of a two-dimensional network of hydrogen-bonded TRISH⁺ {[tris(2-hydroxymethyl)methyl]ammonium} cations and D^- {2-[(2,6-dichlorophenyl)amino]phenylacetate} anions lined up along the [1 0 0] and [0 1 0] directions, respectively. Comparisons between the conformations of the TRISH⁺ cation and the TRIS base (C₄H₁₁NO₃) show that the intermolecular hydrogen bonds have a major influence on determining the structures.
