A novel octacobalt-containing polyoxoniobate, Na6 K12 [H2 Co8 O4 (Nb6 O19 )4 ]⋅39 H2 O, has been prepared by a combination of hydrothermal and diffusion methods. The polyanion H2 Co8 O4 (Nb6 O19 )4 incorporates a tetrameric assembly of Lindqvist-type Nb6 O19 fragments trapping a {Co(II) 4 Co(III) 4 } cluster which comprises a central {Co(III) 4 O4 } cubane core, surrounded by another four Co(II) ions linkers. Furthermore, magnetic measurements show that the compound exhibits antiferromagnetic interactions.
一种新型的八钴含多氧铌酸盐，Na6 K12 [H2 Co8 O4 (Nb6 O19 )4 ]⋅39 H2 O，通过水热和扩散方法的结合制备得到。多阴离子H2 Co8 O4 (Nb6 O19 )4 包含 Lindqvist 型Nb6 O19 片段的四聚体组装，捕获一个{Co(II) 4 Co(III) 4 }簇，其包含一个中心{Co(III) 4 O4 }立方烷核心，被另外四个 Co(II)离子连接体包围。此外，磁性测量表明该化合物表现出反铁磁相互作用。
