Mixing the malonate (mal), 4,4′‐bipyridine, UO 2 (CH 3 COO) 2 · 2H 2 O in different solvent condition gets two compounds (bpy) 2 (H 2 bpy)[UO 2 (mal) 2 ( μ ‐H 2 O)] · 8H 2 O (1) and (H 2 bpy)[UO 2 (mal) 2 ] · 2H 2 O (2) . Both complexes contain seven‐coordinated pentagonal bipyramidal uranium center. Crystal 1 is mononuclear structure and crystal 2 contains dinuclear [(UO 2 ) 2 (mal) 2 ( μ 2 ‐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.
