catena-Poly[[mu-hexanedioato-1kappaO1:2kappaO6-bis[aqua(5-carboxypentanoato-kappaO)copper(II)]]-di-mu-4,4'-bipyridine-1kappaN:1'kappaN';2kappaN:2'kappaN'].
In the title compound, [Cu2(C6H8O4)(C6H9O4)2(C10H8N2)2(H2O)2]n, the square-pyramidally coordinated Cu atoms are bridged by both 4,4-bipyridine and adipate ligands into ladder-like chains, with exo-orientated 5-carboxypentanoate ligands pendant from both side rails. Half of the adipate ligand is related to the other half by inversion symmetry. Interchain O-H...O hydrogen bonds from the aqua ligands to the carbonyl O atoms of the 5-carboxypentanoate ligands are responsible for the formation of two-dimensional grid-like (4,4)-networks, which complete a twofold interpenetration.
