Abstract: The title compound, {[Gd₂(C₁₂O₁₂)(H₂O)₁₀]·4H₂O}_n, consists of an extended network of Gd ions coordinated by the mellitate anions and water molecules. In this complex, each Gd atom involves a dodecahedral coordination environment comprising five water molecules and three O atoms from two separate mellitate anions. The center of mass of the hexaanion [C₆(COO)₆]^6- coincides with a crystallographic inversion center.
