缺位K_10H_5〔Ln(VW_10O_37)_2〕配合物的合成和性质研究

Studies on the Synthesis and Proper is of Vacancy K_(10)H_5[Ln(VW_(10)O_(37))_2]

本文首次报道了缺位K_(10)H_5[Ln(VW_(10)O_(37))_2]XH_2O(Ln=L_^(3+)、C_e^(3+)、P_r^(3+)、N_d^(3+)、S_m^(3+)、E_u^(3+)、G_d^(3-)、T_b^(3+)、D_y^(3+)、Y_b^(3+)+余种配合物的合成方法,无素组成分析与理论值相符。利用IR、UV、XRD和TG—DTA对配合物进行了表征,配合物的热解性质研究表明,其分解温度为400～450℃,还研究了配合物在水溶液中的稳定性。

in this paper a synthetic method of vacancy K_(10)H_5〔Ln(VW_(10)O_(37))_2〕XH_2O(Ln=La^(3+)、Ce^(3+)、P_I^(3+)、Nd^(3+)、Sm^(3+)、Eu^(3+)、Gu^(3+)、Tb^(3+)、Dy^(3-)、Yb^(3-))wast studied the characteristics of IR、UV、XRD and TG—DTA of the new complexes were discussed. The results of Pyrolytis property of the complexes proved that the pyrolysis temperature range of them was:400～450℃。
