Abstract
The formation of bis- and tris-monouclear complexes, MLn, where L is an optically active bidentate ligand is considered and the preferential formation of mixed complexes in the absence of stereoselective effects is explained. The implications of the fact that formation curves (graphs of against pL) for complexes of optically pure and racemic ligands superimpose are examined. The absence of stereoselectivity in the formation of proton and alkaline-earth complexes of (+)- and (±)-1,2-diaminopropanetetra-acetic acid (pdta) and 2,3-diaminobutane-tetra-acetic acid (dimedta) is confirmed.Keywords
