Copper(II) Complexation by 2-((3-((2-Hydroxy-1,1-di(hydroxymethyl)ethyl)amino)propyl)amino)-2-(hydroxymethyl)-1,3-propanediol in Aqueous Solution

  • Published : 1998.02.20

Abstract

The complex formation from Cu(Ⅱ) ion and 1,3-bis(tris(hydroxymethyl)methylamino)propane (bistrispropane) in aqueous solution has been studied potentiometrically and spectrophotometrically. Bistrispropane (btp) coordinates to Cu(Ⅱ) as multidentate. In the btp (L) complex CuL2+, two of the hydroxyl oxygen atoms as well as the amine nitrogens of the ligand are coordinated. In neutral and weakly acidic media, one of the coordinated hydroxyl groups is deprotonated. In basic media, an additional hydroxyl group undergoes deprotonation. The equilibrium constants for the formation of CuL2+, CuLH-1+, and CuLH-2 have been determined. The nature of the coordinate bonds has been deduced from the potentiometric data and the spectra of these complexes.
