The clinical success of metallodrugs is rapidly increasing. The historical use of cisplatin and recently a successful marketing of its clinically advanced derivatives (oxaliplatin, carboplatin, nedaplatin, lobaplatin and heptaplatin) for the treatment of various types of cancer has opened new horizons for metal based drugs. Complexes of cobalt, gold, ruthenium, palladium, manganese and even arsenic are either being marketed or close to get success in clinical trials for the treatment of various diseases. Current review compiles the advances on manganese complexes and their biomedical applications. A possible structure activity relationship has been discussed.

The construction of metallosupramolecular complexes toward interesting topological structures is a critical challenge for chemists. The fluctuation in the synthetic strategy, by keeping the same metal–ligand combination, has proved a very significant approach to construct metallosupramolecular architectures. Herein, by varying the reaction conditions four new DyIII-supramolecular complexes based on a flexible dihydrazone ligand H2L (H2L = bis­(2-hydroxy-3-methoxy­benzylidene)­adipohydrazide) in cooperation with different anions and solvents having formulas [Dy4L4(μ2-N3)2]­(NO3)2·6CH3OH·2H2O (1), [Dy8L8(μ2-CH3OH)4]­Cl8·6CH3OH·14H2O (2), [Dy12L12(μ2-OH)2(OH)6(CH3O)2]­(NO3)2·2CH3OH·14H2O (3), and [Dy12L12(μ2-OH)2(NO3)2(OH)3(CH3O)]­(NO3)4·22H2O (4), have been successfully synthesized and their crystal structures confirmed by single crystal X-ray diffraction studies. The structural study reveals that 1 and 2 have quadruple-stranded helicate and dual triple-stranded helicate supramolecular structures, respectively, while 3 and 4 display “octahedron” cagelike supramolecular structures. The magnetic studies reveal that complexes 1–3 exhibit slow magnetic relaxation behavior, while complex 4 displays a series of typical frequency-dependent relaxation signals at 0 Oe applied dc field which is a rare case in polynuclear 4f single-molecule magnet (SMM) family to date. Interestingly, the distinct magnetic dynamic behavior was noticed for nearly isoskeletal complexes 3 and 4, which can be attributed to the modification of the coordination environment around DyIII ions.

This paper highlights the compounds containing Sb cluster fragments, either synthesized in the solid‐state, discovered from the gas phase, or only theoretically predicted. These Sbn clusters feature unique chemical bonding, fascinating structures, and special stabilities that can be well rationalized by aromaticity or antiaromaticity. A deep understanding to their electronic structures is essential and will greatly facilitate the experimental synthesis of new Sbn cluster‐based materials.
