| Popis: | Two dimeric metal-oxo clusters, {Na4[Co2Sb12(μ3-O)6(μ3-OH)2(μ4-O)3(tartrate)6]·19.5H2O}2 (1) and {KNa3[Ni2Sb12(μ3-O)6(μ3-OH)2(μ4-O)3(tartrate)6]·20H2O}2 (2) were obtained from a simple reaction in aqueous solution without heating. Structural analyses revealed that complexes 1 and 2 feature a cage compound {Sb12} with an encapsulated {Co2}/{Ni2} core, implying the structural diversity in the {Sb12} cage assemblies constructed from potassium antimonyl tartrate as the ligand in aqueous solution. The temperature-dependent magnetic susceptibilities indicated that there are weak ferromagnetic intermolecular or/and intramolecular interactions in 1 and strong ferromagnetic behavior in 2, owing to the strong spin-orbital coupling (1) and Jahn-Teller effect (2). |
