Molecular coolers get Angew. Chem. inside cover story

Molecular refrigerators consisting of unusual fourth-row metal-ion–lanthanide complexes with bridging fluoride ions are presented by M. Evangelisti, J. Bendix, and co-workers in their Communication. The combination of lightweight auxiliary ligands and tunable interactions by choice of metal ion makes these systems interesting modules for low-temperature cooling applications.
