Synthesis and Structural Characterization of a Metal Cluster and a Coordination Polymer Based on the [Mn-6(mu(4)-O)(2)](10+) Unit (Journal article)

Moushi, E. E./ Tasiopoulos, A. J./ Manos, M. J.

A new 1-D coordination polymer {[Mn6O2(O(2)CMc)(10)(H2O)(4)]center dot 2.5H(2)O}(infinity) (1.2.5H(2)O)(infinity) and the cluster [Mn6O2(O-2(O2CPh)(10) (py)(2)(MeCN)(H2O)]center dot 2MeCN (2.2MeCN) are reported. Both compounds were synthesized by room temperature reactions of [Mn-3(mu(3)-O)(O2CR)(6)(L)(2)(L')] (R = Me, L = L' = py, (1.2.5H(2)O)(infinity); R= Ph, L = py, L' = H2O, 2.2MeCN) in the presence of 3-hydroxymethylpyridine (3hmpH) in acetonitrile. The structures of these complexes are based on hexanuclear mixed-valent manganese carboxylate clusters containing the [Mn4(II)Mn(2)(III)(mu(4)-O)(2)](10+) structural core. (1.2.5H(2)O)(infinity) consists of zigzag chain polymers constructed from [Mn6O2(O2CMe)(10)(H2O)(4)] repeating units linked through acetate ligands, whereas 2.2MeCN comprises a discrete Mn-6-benzoate cluster.
