The structure of the title compound, C4H12NO3+.C14H10Cl2NO2-, in the s
olid state consists of a two-dimensional network of hydrogen-bonded TR
ISH+ ([tris(2-hydroxymethyl)methyl]ammonium) cations and D- (2-[(2,6-d
ichlorophenyl)amino]phenylacetate) anions lined up along the [100] and
[010] directions, respectively. Comparisons between the conformations
of the TRISH+ cation and the TRIS base (C4H11NO3) show that the inter
molecular hydrogen bonds have a major influence on determining the str
uctures.
