Dances with carbonyl! Cu II and Ln III react in situ with picolinaldehyde or acetylpyridine, which contain a nucleophilic carbonyl group, by Cannizzaro reaction, aldol reaction, or oxidation reaction. This strategy leads to a series of fascinating [Ln x Cu y ] complexes that either exhibit a magnetocaloric effect or behave as single‐molecule magnets. Calculations have been performed to investigate the magnetic properties. For more details, see the Full Paper by E. Ruiz, M.‐L. Tong et al. on page 17567 ff.
