2N:N'-bis[aqua(4,4'-bipyridine-N)(L-valinato-2N,O)copper(II)] dinitrate dihydrateAbstract: In the title dinuclear complex, [Cu2(C5H10NO2)2(C10H8N2)3(H2O)2](NO3)2·2H2O, each of the two L-valinate anions chelates a CuII center through the amino N and carboxylate O atom, forming a five-membered ring. A 4,4'-bipyridine molecule bridges two water-coordinated Cu atoms, each of which is connected to another 4,4'-bipyridine, giving rise to a square-pyramidal coordination geometry for the CuII centers. The dinuclear dications, nitrate anions and uncoordinated water molecules are linked into a two-dimensional structure.
