The metal-organic frameworks (MOFs) have attracted more and more attention and some MOFs have shown advanced electrical conductivity. Based on previous work about MnTHBQ (THBQ = tetrahydroxy-1,4-benzoquinone), we present two strategies, variation of the ligands' oxidation states and introducing alkali ions (Rb or Cs), to modulate the structures of MOFs and obtained three new MOFs: MnHHB (HHB = hexahydroxybenzene), MnRbTHBQ and MnCsTHBQ. Different from the cubic lattices in the group of of MnTHBQ, they exhibit hexagonal unit cells in the group of 6/. This work highlights the importance of the oxidation state of the ligand in constructing the out-of-plane charge transport pathway and indicates that employing a redox-active ligand or adding alkali metal ions could be an optional strategy for manipulating the characteristics of MOFs.
金属有机框架材料（MOFs）已越来越受到关注，并且一些MOFs已显示出先进的导电性。基于先前关于MnTHBQ（THBQ = 四羟基-1,4-苯醌）的工作，我们提出了两种策略，即改变配体的氧化态和引入碱金属离子（Rb或Cs），以调节MOFs的结构，并获得了三种新的MOFs：MnHHB（HHB = 六羟基苯）、MnRbTHBQ和MnCsTHBQ。与MnTHBQ组中的立方晶格不同，它们在6/组中呈现六方晶胞。这项工作突出了配体氧化态在构建面外电荷传输途径中的重要性，并表明采用氧化还原活性配体或添加碱金属离子可能是操纵MOFs特性的一种可选策略。
