ETUDE STRUCTURALE DU TÉTRAESTER MÉTHYLIQUE DE L'ACIDE ETHANE HYDROXY-1 DIPHOSPHONIQUE-1,1′ ET DU TETRAESTER MÉTHYLIQUE DE L'ACIDE MÉTHANE HYDROXY-1 PHÉNYL-1 DIPHOSPHONIQUE-1,1′

Abstract
Structural study using X-Ray crystallography of the two symmetrical diesters 1 and 2 of the titles has been done. Results are discussed on the basis of the environment of phosphorus atoms and on the molecular geometry around the central carbon atom.
