Di--methacrylato-bis[diaquabis(methacrylato)europium(III)] methacrylic acid disolvate

Z.-G. Zheng, C.-Z. Lin and Q.-Y. Chen

Abstract: In the title centrosymmetric complex, [Eu₂(C₄H₅O₂)₆(H₂O)₄]·2C₄H₆O₂, the unique Eu^III cation is coordinated by seven carboxylate O atoms from four methacrylate ligands and two water molecules in a slightly disorted tricapped trigonal-prismatic environment. Two Eu^III ions are bridged by carboxylate groups, forming a dinuclear complex. The formula unit also contains two molecules of methacrylic acid. In the crystal structure, molecules are linked via intermolecular O-HO hydrogen bonds, forming one-dimensional chains propagating along the b-axis direction
