Abstract

The synthesis, crystal structure, and magnetic studies are reported for a two-dimensional network of mixed valence {Mn₆} cages. The compound contains three different bridging ligands: pivalate, phenylphosphonate, and partially deprotonated triethanolamine. The result of using three bridging ligands is a
complex structure involving a {Mn^III₂Mn^II₄} edge-sharing bitetrahedron that interlinks, forming a layered structure. Weak intercage interactions lead to a remarkably complicated magnetic behaviour, with a phase transition at 2.1 K leading to a canted antiferromagnetic state.
