Novel Copper-Tartrate Coordination Compounds

Abstract

Using the thermometric enthalpy titration methodology, the hexa-ligand species CuT₆ [where T represents the tartrate ion and charges are omitted] has been shown to exist even in dilute tartrate solutions. Kinetic considerations suggest a radical difference between CuT₃ CuT₂ and the more highly coordinated species CuT₃, CuT₄, CuT₅ and CuT₆. It is evident that the hydroxyl groups on the tartrate ion are singularly important contributers to this effect
