The reaction of [Re6Se8(CN)6]4− cluster anions with Ln3+ cations in the presence of thiophene-2,5-dicarboxylate anions in an aqueous solution was studied. Two new framework compounds were synthesized and structurally characterized: [{Yb(H2O)3}2(tdc)-Re6Se8(CN)6]•10H2O (1) and CsK0,5[{Yb4(OH)4(H2O)7,5(NO3)0,5(tdc)2}{Re6Se8(CN)6}]NO3 • 16.5H2O (2) (tdc is the thiophene-2,5-dicarboxylate anion). Compound 1 crystallizes in a wide pH range (3.0–6.5) and has a porous structure with large open voids accessible to guest molecules. Compound 2 crystallizes at pH 6.0–6.5, contains polynuclear cationic complexes [Yb4(OH)4]8+, and also has a framework structure.

基于 [Re6Se8(CN)6]4− 簇阴离子、Yb3+ 阳离子和噻吩-2,5-二羧酸酯接头的金属有机框架

研究了 [Re6Se8(CN)6]4- 簇阴离子与 Ln3+ 阳离子在水溶液中存在噻吩-2,5-二羧酸根阴离子的情况下的反应。合成了两种新的骨架化合物并对其进行了结构表征：[{Yb(H2O)3}2(tdc)-Re6Se8(CN)6]•10H2O (1) 和 CsK0,5[{Yb4(OH)4(H2O)7, 5(NO3)0,5(tdc)2}{Re6Se8(CN)6}]NO3 • 16.5H2O (2)（tdc 是噻吩-2,5-二羧酸根阴离子）。化合物 1 在很宽的 pH 值范围 (3.0-6.5) 中结晶，并且具有多孔结构，并且客体分子可以进入大的开放空隙。化合物 2 在 pH 6.0-6.5 结晶，含有多核阳离子配合物 [Yb4(OH)4]8+，也具有骨架结构。
