By choosing asymmetric L ligands (L = 1-(imidazol-1-yl)-4-(1,2,4-triazol-1-ylmethyl)benzene), Cu2+/Co2+ cations and Keggin clusters as starting materials, two new POM-based zipper-like compounds, Cu(L)4[HPMo12O40]}·4H2O (1) and [Co(L)4][HPMo8VV4O40(VIVO)2]} (2), have been hydrothermally synthesized and characterized by elemental analyses, single-crystal X-ray diffraction, XPS, powder X-ray diffraction
通过选择不对称的L配体(L = 1-(咪唑-1-基)-4-(1,2,4-三唑-1-基甲基)苯),Cu 2+ / Co 2+阳离子和Keggin簇,两个新的基于POM的拉链状化合物Cu(L)4 [HPMo 12 O 40 ]}·4H 2 O(1)和[Co(L)4 ] [HPMo 8 V V 4 O 40(V IV O)2 ]}(2),已经被水热合成并且通过元素分析,单晶X射线衍射,XPS,粉末X射线衍射,IR光谱和TG分析来表征。的结构特征与图1和2的不同之处在于,存在使用分子拉链实现的1D + 1D→3D交叉指结构,其中悬垂的单配位L臂充当牙齿。化合物2示出了朝向不仅减少正常碘化无机分子的双功能电催化活性(IO 3 - )归因于钼中心,而且生物分子如归因于V-中心抗坏血酸(AA)的氧化。
