Two novel hybrid materials based on two kinds of octamolybdate anions and metal-organic frameworks (MOFs), namely, [Ag(8)(L(1))(4)(α-Mo(8)O(26))(β-Mo(8)O(26))(H(2)O)(3)]·H(2)O (1) and [Cu(I)(3.1)Cu(II)(0.5)(β-Mo(8)O(26))(0.5)(ζ-Mo(7)(VI)Mo(V)O(26))(0.5)(L(2))(2)(H(0.8)L(2))(0.5)] (2), where L(1) = 1,1'-(1,3-propanediyl)bis[2-(4-pyridyl)benzimidazole] and L(2) = 1,1'-(1,4-butanediyl)bis[2-(3-pyridyl)benzimidazole], have been successfully synthesized. Crystal structure analysis revealed that 1 is a three-dimensional (3D) framework constructed of silver(I)-organic sheets and two types of (Mo(8)O(26))(4-) isomers. Compound 2 is a rare 3D framework containing copper(I,II)-organic cages and 1D channels occupied by the (ζ-Mo(7)(VI)Mo(V)O(26))(5-) and (β-Mo(8)O(26))(4-) anions. The two compounds were characterized by elemental analysis, IR spectroscopy, diffuse reflectivity spectroscopy, and photoluminescent spectroscopy. In addition, the photocatalytic behavior of 1 was investigated.
基于两种八钼酸盐阴离子和金属有机骨架（MOFs），即[Ag(8)(L(1))(4)(α-Mo(8)O(26))(β-Mo(8)O(26))(H(2)O)(3)]·H(2)O (1) 和[Cu(I)(3.1)Cu(II)(0.5)(β-Mo(8)O(26))(0.5)(ζ-Mo(7)(VI)Mo(V)O(26))(0.5)(L(2))(2)(H(0.8)L(2))(0.5)] (2)，成功合成了两种新型混合材料。晶体结构分析表明，1 是由银（I）-有机片和两种类型的（Mo(8)O(26))(4-)异构体构成的三维（3D）框架。化合物 2 是一种罕见的 3D 框架，包含铜（I，II）-有机笼和 1D 通道，由（ζ-Mo(7)(VI)Mo(V)O(26))(5-)和（β-Mo(8)O(26))(4-)阴离子占据。两种化合物通过元素分析、红外光谱、漫反射光谱和光致发光光谱进行了表征。此外，还研究了 1 的光催化行为。
