✦ Synopsis

Stability constants of Copper(B), Nickel(B), Cohalt(II), Zinc(II), Uranyl(II) and Thorium(IV) a&pates have heen determined by paper electrophoresis. Adipic acid (0.005 mol dmm3) was added to the background electrolyte: 0.1 moldm-3 HC104. The proportions of (CH,),COOH COO-and (CH,),C,O; were varied by changing the pH of the electrolyte. These anions yielded the complexes Zn(CH,),COOH COO+, Co(CH,)&OOH COO+, Ni(CH,),COOH CQO+, Tb(CH,),COOH Coos+, Th[(CH,),COOH COO],, Cu(CH,),C,O, and UO,[(CH,),(C,O,)]~-, whose stability constants are found to be 1O'-B, lo'.', lOa.', 105.2, 10L5.", 102-' and lO".s respectively (fi = 0.1, temp. 40°C).

## Abstract Three ferrocenyl Schiff bases containing a phenol moiety have been formed by 1:1 molar condensation of acetylferrocene with 2‐aminophenol, 2‐amino‐5‐picoline or 2‐amino‐5‐chlorophenol. These ligands form 2:1 complexs with cobalt(II), copper(II), nickel(II), and zinc(II) ions. From the d
