通过水热方法合成了两种新的B-Anderson型多钼氧酸盐[4 ,4′-bpyH2][4 ,4′-bpy H][Cr( OH)6( Mo6O18)](1)和[4 ,4′-bpyH]3[Al(OH)6( Mo6O18)].2 H2O(2) ,通过元素分析、IR光谱和单晶X射线衍射对其进行了表征.化合物1和2都是分离结构.化合物1分子由2个晶体学独立1/2 B-Anderson类型[Cr(OH)6( Mo6O18)]3 -多阴离子,1个双质子化的[4 ,4′-bpyH2]2 +阳离子和1个单质子化的[4 ,4′-bpyH]+阳离子组成,化合物2则是由1个晶体学独立完整的B-Anderson型[ Al( OH)6( Mo6O18)]3 -多阴离子, 3个单质子化的[4 ,4′-bpyH]+阳离子和2个晶格水分子组成.借助4 ,4′-bpy分子间的π-π堆积作用,化合物1和2形成三维超分子结构.
Two novel B-Anderson type polymolybdates [4, 4’-bpyH2] [4, 4’-bpy H] [Cr (OH) 6 (Mo6O18)] (1) and Characterization of [4, 4’-bpyH] 3 [Al (OH) 6 (Mo6O18)] 2 H2O (2) by elemental analysis, IR spectroscopy and single crystal X-ray diffraction showed that both compounds 1 and 2 were The structure of compound 1 consists of two crystallographic independent ½ B-Anderson type [Cr (OH) 6 (Mo6O18)] 3-polyanions, one double protonated [4,4’-bpyH2] Cation and one mono-protonated [4, 4’-bpyH] + cation. Compound 2 is composed of one crystallographic independent B-Anderson type [Al (OH) 6 (Mo6O18)] 3 - polyanion , Three mono-protonated [4, 4’-bpyH] + cations and two lattice water molecules.Compounds 1 and 2 formed three-dimensional supramolecules by π-π stacking between 4 and 4’-bpy molecules structure.
