自1971年Peacock等首次合成以不饱和杂多阴离子作配体的镧系元素杂多配合物[Ln(XW_(11)O_(39)]~(n-)(X=Si,P)以来,这方面的报道较多。过渡元素的引入有可能改善这类化合物的某些活性,尤其是催化活性,但迄今为止尚未见报道,本文首次合成出以TiW_(11)O_(39)~(3-)为配体的镧系元素杂多钨酸盐K_(13)[Ln(TiW_(11)O_(39))_2]·xH_2O(Ln=La,Ce,Pr,Nd,Sm,Eu),并对其IR、UV光谱及热、磁性质进行了测试和初步研究。 Since the first synthesis of lanthanide heteropoly complexes [Ln (XW_ (11) O_ (39)] ~ (n -) (X = Si, P) with an unsaturated heteropolyanion ligand by Peacock et al. In 1971, The introduction of transition elements is likely to improve some of these compounds activity, especially the catalytic activity, but so far has not been reported, this paper for the first time synthesized TiW_ (11) O_ (39) ~ (3) (Ln = La, Ce, Pr, Nd, Sm, Eu), which is a complex of lanthanide heteropolytungstates K_ (13) [Ln (TiW_ (11) O_ (39)) _2] The IR, UV spectra, thermal and magnetic properties were also tested and studied.
