A new 1-D coordination polymer {[Mn 6 O 2 (O 2 CMe) 10 (H 2 O) 4 ]·2.5H 2 O} ∞ ( 1 ·2.5H 2 O) ∞ and the cluster [Mn 6 O 2 (O 2 (O 2 CPh) 10 (py) 2 (MeCN)(H 2 O)]·2MeCN ( 2 ·2MeCN) are reported. Both compounds were synthesized by room temperature reactions of [Mn 3 ( μ 3 -O)(O 2 CR) 6 (L) 2 (L′)] (R = Me, L = L′ = py, ( 1 ·2.5H 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 [Mn 4 II Mn 2 III ( μ 4 -O) 2 ] 10+ structural core. ( 1 ·2.5H 2 O) ∞ consists of zigzag chain polymers constructed from [Mn 6 O 2 (O 2 CMe) 10 (H 2 O) 4 ] repeating units linked through acetate ligands, whereas 2 ·2MeCN comprises a discrete Mn 6 -benzoate cluster.
