Abstract
A di‐manganese(III) complex structure was built by an original approach consisting of a two‐step procedure. First, the mononuclear complex of the manganese(III) with the Schiff base of the salen‐type ligand (H2L) derived from 1,3‐bis(3‐aminopropyl)tetramethyldisiloxane and 3,5‐di‐tert‐butyl‐2‐hydroxybenzaldehyde was prepared. The main feature of note is the 12‐membered chelate ring formed upon coordination of the Schiff base to central atom, which adopts a distorted N2O4 octahedron environment. In the second step, the acetato co‐ligand in this complex is replaced by the carboxylate anion of a dicarboxilic acid, namely adipic acid. This metathesis reaction leads to the formation of dinuclear structure by connecting two manganese centers. The structure, as was determined by X‐ray single crystal diffractometry, elemental and spectral analysis, is permethylated dinuclear complex with long aliphatic bridge. Thermal and magnetic properties were studied. In addition, the formation of magnetically induced stripe‐ordered domains was highlighted by the magnetic force microscopy (MFM) on films born from diluted solution.
