摘要

One novel metallacrown: [Na6Co6(EDBA)(6)(CH3CH2OH)(cH(3)cH(2)O)(2)][CoCl4](2) (1, EDBA = 2,2'-(((ethane-1,2-diylbis(oxy))bis(ethane-2,1-diyl))bis(oxy))dibenzoic anion), has been synthesized under hydrothermal condition. Compound 1 crystallizes in the cubic system with space group Pa-3, and displays a structure with a [24MCNa-6] periphery encapsulating the [12-MCa,-6] inner core. Magnetic investigations suggest that weak ferromagnetic coupling exists between adjacent Co2+ in I.
