The equilibrium constants, <I>K</I><SUB>1</SUB> and <I>K</I><SUB>2</SUB>, between a series of <I>o</I>- and <I>N</I>-substituted anilines and Eu(fod)<SUB>3</SUB> in CCl<SUB>4</SUB> were evaluated using a four-parameter analysis of lanthanoid-induced shifts. It was found that the order of magnitudes of the values of <I>K</I> corrected for the effect of the p<I>K</I><SUB>a</SUB>-value well corresponds to the accessibility of the nitrogen lone-pair to the Eu ion on the complexation.
