| Abstract: | Mixing the malonate (mal), 4,4′‐bipyridine, UO2(CH3COO)2 · 2H2O in different solvent condition gets two compounds (bpy)2(H2bpy)UO2(mal)2(μ‐H2O)] · 8H2O (1) and (H2bpy)UO2(mal)2] · 2H2O (2) . Both complexes contain seven‐coordinated pentagonal bipyramidal uranium center. Crystal 1 is mononuclear structure and crystal 2 contains dinuclear (UO2)2(mal)2(μ2‐mal)2]4‐ subunit. Particularly, Crystal 2 forms the twodimensional supramolecular topology by hydrogen bonds. The sheet constructs from two sorts of chamber, of which the larger one has two water molecular guests.
