Tris(ethyl-enediamine-κN,N')cobalt(III) aqua-tris-(oxalato-κO,O)indate(III).

In the cation of the title compound, [Co(C(2)H(8)N(2))(3)][In(C(2)O(4))(3)(H(2)O)], the Co(III) atom is coordinated by six N atoms from three ethyl-enediamine mol-ecules. The Co(III)-N bond lengths lie in the range 1.956†(4)-1.986†(4)†à . In the anion, the In(III) atom is seven-coordinated by six O atoms from three oxalate ligands and by a water mol-ecule. The cations and anions are linked by extensive O-H⋯O and N-H⋯O hydrogen bonds, forming a supermolecular network.
