• The adsorption of tris (1,10-phenanthroline) copper (II) ([Cu (phen)_3]^<2+>) by a clay mineral has been studied with electron spin resonance (ESR) measurements. The chelate, tris (1,10-phenanthroline) copper (II) ([Cu (phen)_3]^<2+>), is co-adsorbed with a large excess of racemic or enantiomeric [Ru (phen)_3]^<2+>. The spectra of a freezedried sample of a clay-chelate adduct at 77k show that there are two kinds of adsorption states : the one (denoted by state A) is characterized by the parameters of g_11=2.263-2.275 and A_11=151-160G and the other (denoted by state B) by g_11=2.213-2.229 and A_11=150-186G. States A and B are postulated to be the adsorptions on an external surface and in the interlayer space of a clay mineral, respectively. The effects of chelate loading and swelling with organic solvents on the relative abundances of these two states are interpreted on the basis of the above assumption.
