Using slow diffusion methods at room temperature, five uranium coordination polymers were obtained, which either employ glutarate (Glut), terephthalate (TP), or 2-aminoterephthalate (TPNH₂) as bridging systems. Four of these networks are based on the uranyl(VI)-unit, UO₂²⁺, and one formed through the integration of tetravalent uranium as the coordinating metal center. [[UO₂](TP)(H₂O)₂]·2THF (1) arranges as intermeshed one-dimensional (1D) infinite linear chains, locked into a three-dimensional (3D) network through hydrogen bonds with a uninodal 4-coordinated uom topology. [[UO₂](TPNH₂)(H₂O)₂]·2H₂O (2) assembles as intermeshed two-dimensional (2D) layers, also stabilized as a 3D network through hydrogen bonding with a 2-nodal 4-coordinated pts network topology. Na₂[[UO₂]₂(TP)₃]·9H₂O (3) forms parallel layers that are stacked in an AB pattern. Layers possess the uninodal 3-coordinate honeycomb (hcb) motif. Na₂[[UO₂]₂(Glut)₃]·8H₂O (4) assembles as a 3D-coordination network with a uninodal 3-c srs (SrSi₂) topology. The fifth compound contains uranium(IV) and the glutarate entity; U₆(NO₃)₄(Glut)₄(O)₄(OH)₄(H₂O)₆·12H₂O (5). The long-range structure of 5 adopts a 3D open framework, as it includes the flexible glutarate linker, in which U₆O₈ secondary building units assemble as U₆O₃₈ superclusters. These clusters are interlinked by the glutarate spacers resulting in a body centered cubic (bcu) topology.

选定的铀基（VI）配位聚合物和章鱼状铀（IV）团簇的网络维数

使用室温下的缓慢扩散方法，获得了五种铀配位聚合物，它们采用了戊二酸酯（Glut），对苯二甲酸酯（TP）或2-氨基对苯二甲酸酯（TPNH ₂）作为桥联体系。这些网络中的四个基于铀酰（VI）单元UO ₂ ²⁺，并且一个网络是通过四价铀作为配位金属中心的整合而形成的。[[UO ₂ ]（TP）（H ₂ O）₂ ]·2THF（1）排列成相互交织的一维（1D）无限线性链，并通过氢键与单链4锁定为三维（3D）网络。协调的uom拓扑。[[UO ₂ ]（TPNH ₂）（H₂ O）₂ ]·2H ₂ O（2）组装为相互交织的二维（2D）层，也通过与2节点4配位的pts网络拓扑结构进行氢键键合而稳定为3D网络。Na ₂ [[UU ₂ ] ₂（TP）₃ ]·9H ₂ O（3）形成以AB图案堆叠的平行层。图层具有单节点3坐标蜂窝（hcb）图案。Na ₂ [[UO ₂ ] ₂（Glut）₃ ]·8H ₂ O（4）组装成具有单节3-c srs（SrSi ₂）拓扑的3D协调网络。第五化合物包含铀（IV）和戊二酸盐实体；U ₆（NO ₃）₄（胶）₄（O）₄（OH）₄（H ₂ O）₆ ·12H ₂ O（5）。5的远程结构采用3D开放框架，因为它包括灵活的戊二酸接头，其中U ₆ O ₈二级建筑单元组装成U ₆ O ₃₈超级集群。这些簇通过谷氨酸间隔基相互连接，从而形成了体心立方（bcu）拓扑。
