摘      要：A polyoxometalate K_(13)[Gd(GeW_(11)O_(39))_2]·34 H_2 O was synthesized and characterized by elemental analysis,IR spectroscopy, UV spectra, XRD and thermal gravimetric analysis. X-ray single-crystal structural analysis indicates that the title compound crystallizes in the triclinic crystal system. The heteropolyanion of [Gd(GeW_(11)O_(39))_2]^(13) consists of two [GeW_(11)O_(39)]^(8-) vacant Keggin moieties linked via Gd^(3+). Photocatalytic performance of K_(13)[Gd(GeW_(11)O_(39))_2]·34 H_2 O in photodegradation of X-3 B was also *** the reaction time is 180 min, the decoloring rate reaches 71.19%. With the decrease of pH, the decolorization rate increases gradually.
