Increasing the nuclearity and spin ground state in a new family of ferromagnetically-coupled {Ni} disk-like complexes bearing exclusively end-on bridging azido ligands.

The synthesis of a new family of ferromagnetically-coupled {Ni} clusters counterbalanced by various [Ln(NO)] ions is herein described. The resulting compounds are organic chelate-free and the metal ions are exclusively bridged by end-on azido ligands to stabilize a beautiful disk-like topology reminiscent of the structure of the brucite mineral.
