摘要
在H_2O_2溶液中.通过活性粉状白钨酸的解聚制备了二个O_2^(2-):W为2:2型的新的过氧钨酸盐:K_2W_2O_s(O_2)_2·4H_2O(1)和(E_(t4)N^-)_2W_2O_5(O_2)_2·2H_2O(2).用IR、UV和XRD对二个过氧化物进行了表征,并推断了过氧钨酸阴离子的可能结构.
Two new diperoxyditungstates K2W2O5(O2)2 = 4H2O and (Et4N+)2W2O5(O2)2 ?2H2O were prepared by reaction of white powdery tungstic acid with 5% H2O2. Both the peroxytungstates were charater-ized by chemical analysis. IR spectra. UV absorption spectra. X-ray powdery diffraction and thermogram. and the structure of diperoxyditungstate has also been inferred.
