Abstract

The complex formation from Cu(Ⅱ) ion and 2,2-bis(hydroxymethyl)-2,2',2"-nitrilotriethanol (Bistris) in aqueous solution has been studied potentiometrically and spectrophotometrically. Bistris (L) coordinates to Cu(Ⅱ) as tridentate. The complex CuL2+ undergoes deprotonation in neutral and basic media. The deprotonated complexes involve metal-alcoholate coordinate bond in stable chelate structures.
