摘 要：A 1D zigzag polyoxometalate [（CH3）4N]1.50H3.50[Gd（GeW11O39）（H2O）2]·2.5H2O （1） was synthesized by reaction of the monovacant polyanion [α-GeW11O39]8-with Gd3+ ions in aqueous solution and characterized by IR, UV spectra, ICP, and X-ray crystallography. X-ray single-crystal structural analysis indicated that the title compound crystallized in a monoclinic lattice, C2/c space group with a=2.8201（5）, b=2.2885（3）, c=2.4033（4） nm, β=123.875 （2）, V=12.878（4） nm3, Z=8, R1=0.0623, wR2=0.1287. The solid-state structure of the title compound displayed an infinite one-dimensional arrangement built up of [α-GeW11O39]8-polyanions connected by GdIII cations.
