Abstract

A new 1-D coordination polymer { [M n 6 O 2 ( O 2 CMe ) 1 0 ( H 2 O ) 4 ] 2.5 H 2 O } (1 2.5 H 2 O ) and the cluster [M n 6 O 2 ( O 2 ( O 2 CPh ) 1 0 (py ) 2 (MeCN)( H 2 O)] 2MeCN (2 2MeCN) are reported. Both compounds were synthesized by room temperature reactions of [M n 3 ( 𝜇 3 -O)( O 2 CR ) 6 (L ) 2 ( L )] (R = Me, L =  L  = py, (1 2.5 H 2 O ) ; R = Ph, L = py, L  =  H 2 O, 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 [ M n 4 I I M n 2 I I I ( 𝜇 4 -O ) 2 ] 1 0 + structural core. (1 2.5 H 2 O ) consists of zigzag chain polymers constructed from [M n 6 O 2 ( O 2 CMe ) 1 0 ( H 2 O ) 4 ] repeating units linked through acetate ligands, whereas 2 2MeCN comprises a discrete M n 6 -benzoate cluster.
