| Abstract: | Three unprecedented 2D architectures made up of sandwich‐type tetra‐metal‐substituted polyoxotungstates and transition‐metal complexes, Cu(dien)(H2O)]2{Cu(dien)(H2O)]2‐Cu(dien)(H2O)2]2Cu4(SiW9O34)2]}? 5H2O ( 1 ; dien=diethylenetriamine), Zn(enMe)2(H2O)]2{Zn(enMe)2]2Zn4‐ (HenMe)2(PW9O34)2]}?8H2O ( 2 ; enMe =1,2‐diaminopropane), and Zn(enMe)2‐(H2O)]4Zn(enMe)2]2{(enMe)2{Zn‐ (enMe)2]2Zn4(HSiW9O34)2]}{Zn‐ (enMe)2(H2O)]2Zn4(HSiW9O34)2]}}? 13H2O ( 3 ) were hydrothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, and single‐crystal X‐ray diffraction. Compound 1 consists of anions Cu4(SiW9O34)2]12? linked by copper complexes into a 2D structure, whereas 2 is constructed from novel inorganic–organic hybrid anions Zn4(HenMe)2(PW9O34)2]8? linked by zinc complexes into a 2D structure. The most interesting is the unique 2D network 3 , which consists of anions Zn4(PW9O34)2]10? with two types of bridging groups: zinc complexes and enMe ligands. |
