摘要
合成并表征了一系列化合物Ａｌ２Ｍｏ３－ｘＷｘＯ１２．ｘ＝０，０．５，１．０，１．５和２．０的化合物是以单斜晶系Ａｌ２（ＭｏＯ４）３为基质的化合物和固溶体，空间群为Ｐ２１／ａ；ｘ＝２．５和３．０的标题化合物是以正交晶系Ａｌ２（ＷＯ４）３为基质的固溶体和化合物，空间群为Ｐｂｃｎ．利用粉末Ｘ射线衍射图谱全谱拟合的方法精修了ｘ＝０，０．５，１．０，１．５，２．０的标题化合物的结构。
The title compounds were synthesized and characterized as P2\-1/a space group in monoclinic phase for x=0, 0\^5, 1\^0, 1\^5, 2\^0 and Pbcn space group in orthohombic phase for x=2\^5, 3\^0. The structure refinments were success for x=0, 0\^5, 1\^0, 1\^5, 2\^0 using laboratory X\|ray data. The preliminary interpretation of the phase transition was discussed on the basis of the structural parameters.
