The ligand is highly basic and the stepwise protonations is dominated by extensive proton relocations. The Cu2+ complexes exhibited very high stability, those of Zn2+, Cd2+, Pb2+, La3+, Sm3+, Gd3+,Ho3+ and Lu3+ presented high stability while that of Ca2+ had lower stability, as expected. Three phosphonate moieties are bound in the Cd2+ complex and several isomer species were present in solution of the Zn2+ complex. A major isomer was stabilised in solution upon heating where only one of the methylphosphonate arms was coordinated to the metal centre and this isomer probably adopts a distorted square pyramidal (type I conformation of the cyclam ring)." . .
