A linear relation between the molar susceptibility (&khgr;m) and the number of electrons in the cation has been established for the organic salts of (i) Mg, Zn, and Cd, and (ii) Ca, Sr, and Ba, containing a common anion. This relation has been successfully used to evaluate (a) the susceptibilities of anions in combination with cations of these two subgroups and (b) the susceptibilities of the cations themselves. It has been pointed out that this method of evaluation of ionic susceptibilities enables one to predict unknown cases with considerable accuracy.
