Thermodynamic stability constants of beryllium(ii) and p-substituted N-phenyl benzohydroxamic acid complexes

Abstract

The thermodynamic stability constants of beryllium(II) complexes of p-substituted N-phenylbenzohydroxamic acids have been determined in 50% v v aqueous dioxan at 35°. The effect of methoxy, methyl, chloro, bromo, and nitro groups as substituents is discussed. There is a linear relationship between log K 1 and p K a and the Hammett equation is applicable. The beryllium complexes have been compared with those of Cu, Zn, Ni and Mn.
