Enantiopure single crystals of extended metal atom chains display exceptionally large optical X-ray dichroisms at the Co K-edge.

A trinuclear iron cluster possesses ferromagnetically coupled high-spin FeII centers and displays slow relaxation of the magnetization under applied field.

A series of tricobalt EMACs with halide axial ligands demonstrate diverse spin-crossover behaviors as a function of the molecular geometry and the nature of the axial ligand.

The structural and magnetic properties of dinuclear FeII and CoII complexes, synthesized through the targeted use of mer-coordinating boratriazine and azido bridging ligands are presented, which exhibit large spin ground states due to ferromagnetic interactions.
