Single-crystal X-ray diffraction (XRD) analysis of 1 reveals a layered structure of UO6, UO7, and CoO4N2 units that are linked by the carboxyphosphinate ligands. Imidazole molecules modify the layer by coordinating to Co centers. Similarly, 2 is a mixed zinc-uranyl carboxyphosphinate with different topological two-dimensional structure and the decorated moiety is a bpi coligand. When in the presence of bridging dib coligands, the mixed cadmium–uranyl carboxyphosphinate sheets of 3 are pillared by dib forming a framework structure. The isostructures of 4 and 5 are also pillared frameworks constructed by a mixed heterometallic uranyl phosphinate layered subnet that is different from that of 3. The structures of 68 are isotype and very special in that they consist of distinct [M­(dib)2(H2O)2]n2n+ cationic and [(UO2)3(L)4]n2n– anionic subnets. Such two sheets are packed alternatively and interact via hydrogen bond forming three-dimensional supramolecular structures. %I ACS Publications
