A heterobimetallic [Mn5(II)Cu5(II)] nanowheel modulated by a flexible bis-oxamate type ligand.

The synthesis, crystal structure and preliminary magnetic characterization of a new heterobimetallic [Mn5(II)Cu5(II)] wheel containing a flexible bis-oxamate type ligand are described. This decanuclear compound exhibits a relatively strong intra-wheel antiferromagnetic interaction leading to a ground spin state S = 10.

A pH-triggered bistable copper(II) metallacycle as a reversible emulsion switch for biphasic processes.

A unique bistable copper-metallacyclic complex is used as an elegant molecular switch for the reversible formation of emulsions by simple pH variation. This switch may have several exciting applications in biphasic processes such as catalysis and separation science technologies.
