Synthesis and Structural Characterization of a Metal Cluster and a Coordination Polymer Based on the [Mn6(μ4-O)2]10+Unit

Abstract

A new 1-D coordination polymer [M(CMe(O]2.5O (12.5O and the cluster [M((CPh (py(MeCN)(O)]2MeCN (22MeCN) are reported. Both compounds were synthesized by room temperature reactions of [M(-O)(CR(L()] (R = Me, L =  = py, (12.5O; R = Ph, L = py,  = O,22MeCN) 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 [(-O structural core. (12.5O consists of zigzag chain polymers constructed from [M(CMe(O] repeating units linked through acetate ligands, whereas22MeCN comprises a discrete M-benzoate cluster.
