Metal complexes of 4,11-dimethyl-1,4,8,11-tetraazacyclotetradecane-1,8-bis(methylphosphonic acid) - Thermodynamic and formation/decomplexation kinetic studies

Abstract

Bis(phosphonic) acid derivative of cyclam was synthesized by an improved synthesis. Thermodynamic stability of divalent metal complexes was determined.

Formation and decomplexation kinetics of complexes with divalent copper, zinc and cadmium was investigated.
