%X Hydrothermal reactions of uranyl
acetate and a series of transition
metal acetates with a carboxyphosphinate and auxiliary N-donor ligands
gave rise to the formation of eight heterometallic uranyl-organic
assemblies, namely, Co(im)2(UO2)3(L)4 (1), Zn(bpi)(UO2)(L)2 (2), Cd(dib)(UO2)(L)2 (3), M(dib)(UO2)2(L)3 (M =
Cd (4), Mn (5)), and [M(dib)2(H2O)2][(UO2)3(L)4]·nH2O (M = Co (6, n = 2), Ni
(7, n = 2), Cu (8, n = 0)) [H2L = (2-carboxyethyl)(phenyl)phosphinic acid (CPP), im
= imidazole, bpi =1-(biphenyl-4-yl)-1H-imidazole, dib =1,4-di(1H-imidazol-1-yl)benzene].
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 6–8 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.
