Abstract: The crystal structure of the title compound, [Y₂(C₁₀H₈N₂O₄)₂(C₁₀H₉N₂O₄)₂(H₂O)₂][Y(C₁₀H₇N₂O₄)(H₂O)₅]₂·6H₂O, contains two independent molecular units, viz. a centrosymmetric dimeric [Y(C₂₀H₈N₄O₈)₂(H₂O)]₂ unit and a single [Y(C₁₀H₇N₂O₄)(H₂O)₅] unit. Both Y^III ions have coordination number 8, with distorted dodecahedra as coordination polyhedra. Numerous intermolecular hydrogen bonds link the molecular units and three additional independent water molecules into a three-dimensional network.
