Complexes of Cu(II) with 2,2'-bipyridyl and maleic or phthalic acid.
The stability constants of ternary copper(II) complexes with 2,2'-bipyridyl and a dicarboxylic acid (maleic and phthalic) have been determined by means of pH-titrations at 25 +/- 0.1 degrees and an ionic strength of 0.1M (Na,H)ClO(4). The stabilities of ternary complexes are compared with those of similar complexes and related to the size of the chelate rings and the nature of the dicarboxylic ligands.
