摘要
Mixing the malonate (mal), 4,4'-bipyridine, UO2(CH3COO)(2)(.)2H(2)O in different solvent condition gets two compounds (bpy)(2)(H(2)bpy)[UO2(mal)(2)(mu-H2O)](.)8H(2)O (1) and (H(2)bpy)[UO2(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 [(UO2)(2) (mal)(2)(mu(2)-mal)(2)](4-) subunit. Particularly, Crystal 2 forms the two-dimensional supramolecular topology by hydrogen bonds. The sheet constructs from two sorts of chamber, of which the larger one has two water molecular guests.
