摘要：

Addition of aqueous H2O2 to a solution of Co(O(2)CMe)(2) . 4H(2)O and L [L = 1,2-bis(2,2'-bipyridyl-6-yl)ethane] in a 3:1 molar ratio, followed by addition of LiClO4, allows isolation of [Co8O4(OH)(4)(O(2)CMe)(6)L(2)](ClO4)(2) 1 which contains 4Co(II), 4Co(III); the core comprises three face-sharing cubane units, and magnetic susceptibility studies confirm the paramagnetic nature of the compound and the presence of high-spin Co-II ions.
