Implication

Structural analysis reveals monomeric manganese(III) and valence-trapped hexanuclear manganese(III/IV) clusters, highlighting polyamine ligand coordination in polynuclear metal assemblies.

Key Points

Synthesize and structurally characterize coordination complexes formed between the polyamine ligand 1,5,8,12-tetraazadodecane (3,2,3-tet) and manganese ions across different oxidation states.
Synthesized manganese coordination compounds using the linear tetraamine ligand 1,5,8,12-tetraazadodecane (3,2,3-tet) in the presence of bridging and auxiliary ligands.
Determined single-crystal and molecular structures via X-ray crystallographic diffraction techniques.
Elucidated the crystal and molecular structure of the mononuclear manganese(III) complex [trans-Mn(3-IOBz)2(3,2,3-tet)](ClO4).
Resolved the structure of the valence-trapped mixed-valent hexanuclear array [Mn6(3,2,3-tet)4O6(OAc)3]I5·2H2O·4C4H8O, verifying distinct manganese(III) and manganese(IV) oxidation centers.
