“…The enhancement in bacterial inhibition activity may depend upon the charge distribution, size, shape and redox potential of the metal complexes. Moreover, pharmacokinetic and steric factors also play a vital role in determining the potency of an antimicrobial agent . A complex C 59 , [Mn II ( a L 59 )( b L 59 )Cl] was prepared with 1,10‐phenanthroline ( a L 59 ) and a mono negative tridentate guaifenesin ligand ( b L 59 ) (OOO coordination sites).…”

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.

An original co‐ligand association, consisting of 4,4'‐azopyridine and 1,3‐bis(carboxypropyl)tetramethyldisiloxane, is used for complexing MnII, to obtain a 2D dinuclear coordination array having infinite horizontal dimensions and nanometric thickness. Due to the shielding effect of the tetramethyldisiloxane units facing outwards on both sides, the sheets are free of any chemical or physical intermolecular interactions, as crystallographic analysis reveals. The compound shows two glass transitions, at –51 and 33 °C, and begins to decompose at 292 °C. The co‐existence in the structure of the highly hydrophobic tetramethyldisiloxane spacers and the polar metal complexed units confers amphiphilic character to the compound, making it capable of reducing the surface tension of the DMF, from 35.8 to 29.4 mN/m, at a critical micellar concentration around 1 wt.‐% complex. The presence of aggregates in solution is evidenced by dynamic light scattering. The light sensitive azopyridine units make the compound photo‐responsive. This behavior occurs both in solution as well as in the film, where the compound self‐assembles in micellar morphology when UV‐irradiated. Both conductivity and dielectric permittivity of the film increase as a result of trans–cis configuration. Magnetic measurement data indicate two antiferromagnetic coupled spins, S = 5/2, that are able to interact with small external magnetic field, i.e., during MFM scanning.
