摘要

New dodecanuclear phenylphosphonate-bridged Co(II) complexes [(μ_2~-THF)_5(η-HPiv)Co_(12)(μ_3~- OH)_4(μ_6~-O_3PPh)_4(μ-Piv) _(12)]·THF·2_(66) (1·THF· 2_(66)), [(μ_2~-THF)_6Co _(12)(μ_3~-OH)_4(μ_6~-O _3PPh)_4(μ-Piv)_(12)]·3THF (2·3THF) and [(μ_2-Hmhp)_6Co_(12)(μ_3~-OH) _4(μ_6~-O_3PPh)_4(μ-Piv) _(12)]·6.5MeCN (3·6.5MeCN) have been synthesized by the reaction of the cobalt(II) pivalate polymer {Co(Piv)_2}_n (Piv is the pivalate anion), as a source of metal fragments containing cobalt(II) atoms, with potassium phenylphosphonate (K_2PO _3Ph) in the presence of neutral O-donor additional ligands like molecules of THF or 6-methyl-2-pyridone (Hmhp). The structures of the dodecanuclear complexes 1-3 were determined by using single-crystal X-ray diffraction data. The magnetic properties of the compounds showed that complexes 1 and 3 exhibit antiferromagnetic exchange interactions between the magnetic centers. The stability of compounds 1 and 3 were studied using thermogravimetric analysis.
