Ferrimagnetic-like coupling in ordered one-dimensional systems. Homo- and hetero-metallic chains in EDTA complexes
Abstract
We report on the magnetic behaviour of one-dimensional exchange-coupled systems MM′EDTA·6H2O, where M and M′ are two host sites for first-row transition metals (Co, Ni, Cu).
The isolated complexes are either homometallic chains with one kind of magnetic cation or heterometallic chains with two distinct cations in the regular sequence ⋯A—B—A—B⋯.
