Abstract
If a strong base is added to solutions containing complexes of trivalent antimony with aminopolycarboxylates, these ligands are displaced, and oversaturated solutions of antimony (III) hydroxide are formed. This reaction has been used to investigate the formation of complexes of SbIII with the following ligands: N′‐hydroxyethyl‐ethylenediamine‐N,N,N′‐triacetate ion, ethylenediamine‐N,N,N′,N′‐tetraacetate ion, 1,2‐diaminocyclohexane‐N,N,N′,N′‐tetraacetate ion, and diethylenetriamine‐N,N,N′,N″,N″‐pentaacetate ion.
