Bis(N,N′-dimethylethylenediammonium) tris(oxalato-κ2O1,O2)cobaltate(II) dihydrate: an ion-pair complex

The CoII ion in the title complex, (C4H14N2)2[Co(C2O4)3]·2H2O, is coordinated by three oxalate ions, resulting in a distorted octahedral geometry. Two uncoordinated water molecules are present in asymmetric unit. Intermolecular N—H...O and O—H...O hydrogen bonds between the different entities stabilize the crystal structure.
