Rb2Co(C2O4)2·4H2O consists of isolated [Co(C2O4)2·2H2O] octahedra which are connected only by hydrogen bonding of the water molecules. Rb2CoCl2(C2O4) consists of chains of Co2+ cations connected via oxalate bridging ligands. In K2Li2Cu(C2O4)3·2H2O, the metal cations are interconnected by oxalate ligands forming a novel three-periodic network.
