Rezumat

A new series of hexanuclear mixed-valent carboxylate coordination clusters of the type [Mn₆O₂(O₂CR)₁₀L₄] (R = CMe₃; CHMe₂) featuring a {Mn^II₄Mn^III₂(μ₄-O)₂} core of composition [Mn₆O₂(O₂CCMe₃)₁₀(Me₃CCO₂H)₃(EtOH)]·(Me₃CCO₂H) (1), [Mn₆O₂(O₂CCMe₃)₁₀(Me₃CCO₂H)₂ (EtOH)₂]·2(EtOH) (2) and [Mn₆O₂(O₂CCMe₃)₁₀(Me₃CCO₂H)₂(MeOH)₂]·2(MeOH)·H₂O (3), and coordination polymers which incorporate such clusters, namely [Mn₆O₂(O₂CCHMe₂)₁₀(pyz)(MeOH)₂]_n (4), {[Mn₆O₂(O₂CCHMe₂)₁₀(pyz)_1.5(H₂O)]·0.5(H₂O)}_n (5), and [Mn₆O₂(O₂CCMe₃)₁₀(HO₂CCMe₃)₂(en)]_n (6), have been synthesized (where pyz = pyrazine, en = ethyl nicotinate). The modification of the cluster surface by a diverse combination of capped or bridging ligands attached to peripheral Mn^II atoms results in discrete clusters with a closed hydrophobic exterior shell in 1 and 2, supramolecular chains built through hydrogen bonded solvent molecule clusters in 3, linear coordination polymers in 4 and 6 or a ladder-like coordination polymer in 5. The H-bonded coordination polymers 4 and 5 form supramolecular layers in crystals.
