摘要: 本文报道了α和β-[SiW9O37M3(H2O)3]1-(M=Al3+,Ga3+,In3+)钾、铯盐的合成和性质。6种化合物的钨-183核磁共振谱都含有2个峰,相对强度为2:1,表明其阴离子分别具有Aα和Aβ型Keggin结构,即3个MO6八面体是角顶共用。

关键词: 三取代Keggin结构, 杂多阴离子, 含3A族元素杂多钨酸盐

Abstract: Salts of the title anions have been prepared from the lacunary tungstates α- and β-SiW9O3410- and characterized by elemental analysis, spectroscopy, polarography.Tungsten-183 NMRspectra of the title complexes consist of two lines (intensity ratio 2:1) as expected for the C3Vstructure of trisubstituted α- and β-Keggin anions.

Key words: Trisubstituted Keggin structure, Heteropolyanions, Heteropolytungstate containing 3A group elements
