Abstract
- Cyclic trinuclear homo-metal complexes, [{Fe(L<superscript>3+2</superscript>Br)py}<subscript>3</subscript>] (1) and [{Mn(L<superscript>3+2</superscript>Br)}<subscript>3</subscript>(py)<subscript>2</subscript> MeOH] (2), along with a hetero-metal complex, [FeMn<subscript>2</subscript>(L<superscript>3+2</superscript>H)<subscript>3</subscript>(DMF)<subscript>3</subscript>] (3), were synthesized using asymmetric ditopic ligands (H<subscript>3</subscript>L<superscript>3+2</superscript>H: 2-(2-hydroxyphenyl)-6-ol-5-(salicylideneamino)benzoxazole, H<subscript>3</subscript>L<superscript>3+2</superscript>Br: 2-(2-hydrox-5-bromoyphenyl)-6-ol-5-(5-bromosalicylideneamino)benzoxazole). The molecular structure of 1 is characterized by a tripod structure with three-fold symmetry, where an enantiomer pair forms a dimeric capsule with dimensions of approximately 3 × 1.6 × 1.6 nm<superscript>3</superscript>. Complexes 2 and 3, which lack three-fold symmetry, exhibit similar molecular structures to previously reported complexes with these ligands, but do not form a capsule structure. Magnetic measurements of 1–3 reveal the presence of significantly weak antiferromagnetic interactions between the metal ions. [ABSTRACT FROM AUTHOR]
