In the cation of the title compound, [Co(C2H8N2)3][In(C2O4)3(H2O)], the CoIII atom is coordinated by six N atoms from three ethylenediamine molecules. The CoIII-N bond lengths lie in the range 1.956 (4)-1.986 (4) Å. In the anion, the InIII atom is seven-coordinated by six O atoms from three oxalate ligands and by a water molecule. The cations and anions are linked by extensive O-HO and N-HO hydrogen bonds, forming a supermolecular network.
