[V6O13(OCH2)3C(4-CONHC5H4N)}2]2– (1) reacts with divalent first-row transition-metal cations (MnII, CoII, NiII, or ZnII) to yield crystalline linear zwitterionic coordination polymers (1M). The zwitterionic coordination chains are connected to each other by hydrogen bonds to form a 3D network. Microporous channels are formed along the packing axes of the 2D networks. All four compounds exhibit almost
氧化还原活性双(吡啶基)封端的六钒酸盐 [V6O13(OCH2)3C(4-CONHC5H4N)}2]2– (1) 与二价第一排过渡金属阳离子(MnII、CoII、NiII 或 ZnII)反应) 以产生结晶线性两性离子配位聚合物 (1M)。两性离子配位链通过氢键相互连接以形成 3D 网络。沿二维网络的堆积轴形成微孔通道。所有四种化合物都表现出几乎相同的细胞参数、空间群 (P) 和晶体形态。这些材料已通过 X 射线晶体学、1H 和 51V NMR、IR、UV/Vis、元素分析和 TGA 进行表征。所有化合物 1M 都被化学还原剂如苯肼和 NaBH4 在四氯化碳中可逆还原,其中六钒酸盐不溶。(© Wiley-VCH Verlag GmbH & Co.
