Various monoionic montmorillonites were treated with an ethanol solution of O-(P-Toluenesulfonamido) aniline (abber. TSA) which is a highly specific reagent for precipitating cupric-chelate. These montmorillonite specimens were immersed in the ethanol solution of TSA for 4-5 days, and then air-dried. After this treatment, monoionic montmorillnites saturated with H^+, Fe^<3+>, CO^<2+>, Ni^<2+>, Mn^<2+>, Zn^<2+>, Cd^<2+>, Hg^<2+>, Mg^<2+> and Sr^<2+> did not show remarkable change, in their basal spacings (14.0-15.4 Å) , whereas Cu^<2+> saturated one clearly gave a basal spacing of 21 Å under the condition of 0.3g TSA/1g specimen. These results indicate that the formation of the complex of montmorillonite-TSA having a 21 Å spacing is due to the specificity of TSA. The authors inferred the structure of the complex having an upright orientation of TSA-assemblage in an interlayer of montmorillonite.
