BIMETALLIC RANDOM CHAINS ; INFLUENCE OF THE PREPARATION PROCEDURE ON STRUCTURE OF AMORPHOUS MM' (EDTA)nH2O COMPLEXES

摘要

The local structure of the amorphous series MM' (EDTA)nH2O (M,M' = Mn, Ni, Co, Cu) is discussed through LAXS, magnetic and spectroscopic measurements. Similarly to the crystalline phase, this structure shows a chain stacking characterized by alternating environments for the metal ions M and M'. The influence of the preparation procedure on the structure is reported.
