Two original acid derivatives of methylene diphosphonic acid (MDP) with two inequivalent phosphorus atoms have been synthesised: [(thiophosphonato)-methyl] phosphonic acid, (MDPS), and [(isopropylamido phosphonato)-methyl] phosphonic acid, (MDPN). A potentiometric study allowed to define the stoechiometry of the complex formed between MDP and magnesium (II) in alcaline medium and a 31P NMR study proved the dissymetric structure of this MDPMg2+ complex. The displacement of the coordination equilibrium between Black Eriochrome T and magnesium (II) permitted to compare the coordination strength of MDP, MDPS and MDPN with the cation Mg2+.
