合成了LnL(L代表配体)型镧系硅钨杂多配合物K_5[LnSiW_(11)O_(39)],再分别与盐酸胍盐反应,得(CN_3H_5)_5[LnSiW_(11)O_(39)]·nH_2O。阳离子交换试验证明Ln~(3+)居于配合物内界。用IR、UV、DSC-TGA和XRD分析,对杂多配合物进行了表征。
LnSiW_ (11) O_ (39)] was synthesized with LnL (ligand of L) and then reacted with guanidinium hydrochloride to obtain (CN_3H_5) _5 [LnSiW_ (11) O_ 39)] · nH 2 O. Cation exchange experiments show that Ln ~ (3 +) resides in the complex interior. Heteropoly complexes were characterized by IR, UV, DSC-TGA and XRD.
