Poly[dimethylammonium aquadi--oxalato-europate(III) trihydrate]

Y.-Y. Yang, S.-B. Zai, W.-T. Wong and S. W. Ng

Abstract: In the crystal structure of the polymeric title compound, (C₂H₈N)[Eu(C₂O₄)₂(H₂O)]·3H₂O, the independent oxalate that lies on a general position chelates to two Eu atoms, as do the other two oxalates that lie on different centres of inversion, the bridging mode of the oxalates giving rise to a three-dimensional anionic network. The water-coordinated Eu atom exists in a tricapped trigonal-prismatic geometry. The cations and solvent water molecules occupy the cavities of the network and are involved in hydrogen bonding with each other and with the network.
