摘要
以H_4SiW_(12)O_(40)为原料,合成了两种含有稀土铕、钕和5-氟尿嘧啶的多金属氧酸盐:K_(11)(C_4H_4FN_2O_2)_2Eu(SiW_(11)O_(39))_2·20H_2O(简写为FEuSiW)和K_(11)(C_4H_4FN_2O_2)_2Nd(SiW_(11)O_(39))_2·18H_2O (简写为FNdSiW),并采用~1H NMR、IR、XRD和TG-DTA对其结构进行了的表征。
Taking H_4SiW_(12)O_(40) as material, the paper synthesizes tow polyoxometalates containing rare earth Nd, Eu and 5-fluorouracil. They are K_(11)(C_4H_4FN_2O_2)_2Eu(SiW_(11)O_(39))_2.20 H_2O(simplified as FEuSiW) and K_(11)(C_4H_4FN_2O_2)_2Nd(SiW_(11)O_39)_2·18 H_2O(simplified as FNdSiW). Their structure are characterized with ~HNMR, IR, XRD and TG-DTA.
