摘要

硫族锗以其灵活的结构和丰富的性质在无机化学领域引起了广泛的关注。以碱金属为结构导向剂，采用溶剂热法合成了5种含过渡金属锰、锌、镉的新型锗硫族化合物。Rb2MnGeSe4(1)、Cs2MnGeSe4(2)、Cs2ZnGeSe4(3)为一维链式结构，Rb2Zn2GeSe4·H2O(4)、Rb2CdGeSe4(5)为二维层状结构。对化合物1 ~ 5的电子结构、带隙和光电流响应进行了全面分析。由于化合物4和5的二维层状结构，我们研究了它们的离子交换性质。化合物4和5具有优异的离子交换性能，可作为潜在的离子交换材料用于核废水中放射性元素的吸附。

Five Transition Metal-Mixed Germanium Chalcogenide Materials: Solvothermal Syntheses, Crystal Structures, Photoelectric Response Properties, and Ion-Exchange Properties

Germanium chalcogenides have attracted wide attention in inorganic chemistry because of their flexible structure and rich properties. Five new germanium chalcogenides containing transition metals such as manganese, zinc, and cadmium were synthesized by solvothermal methods using alkali metals as structural directing agents. Rb₂MnGeSe₄ (1), Cs₂MnGeSe₄ (2), and Cs₂ZnGeSe₄ (3) have a one-dimensional chain structure and Rb₂Zn₂GeSe₄·H₂O (4) and Rb₂CdGeSe₄ (5) have a two-dimensional layer structure. The electronic structure, band gap, and photocurrent response of compounds 1–5 have been comprehensively analyzed. Due to the two-dimensional layered structure of compounds 4 and 5, we studied their ion-exchange properties. Compounds 4 and 5 showed excellent ion-exchange properties and could be used as potential ion-exchange materials for the absorption of radioactive elements in nuclear wastewater.
