A hexanuclear manganese(III) complex constructed from triangular-shaped [Mn3O] units with azide bridge

Toward Multifunctional Materials Incorporating Stepladder Manganese(III) Inverse-[9-MC-3]-Metallacrowns and Anti-Inflammatory Drugs

“…In the literature, there are plenty of polynuclear trivalent metal complexes with salicylaldoxime as ligands, where the metal ion is Fe(III) 17,18 or, in most cases, Mn(III). 19−29 Concerning the nuclearity of these complexes, the majority of the existing reports include dinuclear, 17 trinuclear, 20,25 tetranuclear, 18,23 and hexanuclear 22−29 complexes hosting diverse ligands such as amides, 26 azides, 27,28 halides, 29 perchlorate, 20 and diverse carboxylate ligands. 22−24 Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most frequently used analgesic, anti-inflammatory, and antipyretic agents despite their known gastrointestinal and renal side-effects.…”

“…The doubly deprotonated ligand of salicylaldoxime (sao 2– ) is potentially a tridentate binucleating ligand, which may be coordinated to the metal ions via its nitrogen and oxygen atoms participating in the formation of the metallacrown ring. In the literature, there are plenty of polynuclear trivalent metal complexes with salicylaldoxime as ligands, where the metal ion is Fe­(III) , or, in most cases, Mn­(III). − Concerning the nuclearity of these complexes, the majority of the existing reports include dinuclear, trinuclear, , tetranuclear, , and hexanuclear − complexes hosting diverse ligands such as amides, azides, , halides, perchlorate, and diverse carboxylate ligands. − …”
