A rare Mn9 micro3-oxo-centered mixed-valent cluster [Mn9O7(O2CPh)11(thmn)(py)2 (H2O)3] (1) is prepared by assembling an oxo-centered MnIIMnIII2 triangle, [Mn3O(O2CPh)6(py)2(H2O)].0.5MeCN, as the secondary building unit in the presence of a tripodal alcohol, 1,1,1-tris(hydroxymethyl)nitromethane (H3thmn), as the capping ligand. Complex 1 was formed along with a minor byproduct, [Mn6O2(O2CPh)10(MeCN)4] (2). Complex 1 was characterized by X-ray single-crystal structure analysis and was… Expand

Two new Mn(II) coordination polymers, namely {[Mn3L2(pbbm)]·CH3CN}n (1) and [Mn3L2(CH3CN)2]n (2) (pbbm = 1,1′-(1,5-pentane)bis-benzimidazole) have been prepared using a 3,4-bi(4-carboxyphenyl)benzoicExpand
Synthesis of mixed-valence hexanuclear Mn(II/III) clusters from its Mn(II) precursor: variations of catecholase-like activity and magnetic coupling.
It is found that the mixed valent Mn6 complexes (2 and 3) are much more active towards aerial oxidation of catechol compared to the Mn(II) complex (1), and variable-temperature magnetic susceptibility measurements showed the presence of antiferromagnetic coupling in all three complexes. Expand
