【摘要】 本文用改进的方法首次合成出 K₇A（H₂O）CuW₁₁O₃₉·xHzO（A=Al,Ga,In）.通过化学分析、离子交换、IR,UV,x-射线衍射等对合成产物进行了鉴定.在此基础上对其热性质和在溶液中的某些性质进行了研究.在 IR 谱中,随周期数增加,振动频率向低波数移动.x-射线衍射表明,对给定的杂原子在杂多阴离子与不同的3A 主族元素作用中差别不大.更多还原

【Abstract】 In this paper ,the complexes K₇A（H₂O）CuW₁₁O₃₉·xH₂O（A=Al,Ga,In）has been first prepared by an improved method.We have examinated the synthetic product by the chemical analysis,ionic exchange,IR,UV,X-ray.According to these,We have studied their thermal property as well as some properties in the solution.In the IR spectra ,the vi- brational frequency shift towards lower frequency while the periodic number increasing. X-ray indicated that differences in behavior of the group 3A element substituted het- eropolyanions are generally small for a given central atom.更多还原
