摘要
合成了未见文献报道的4:30系列钨磷杂多酸盐Na16P4W30M4(H2O)2O112·xH2O(M=Sn2+,Cd2+),并通过元素分析、红外光谱、紫外-可见光谱及183WNMR进行了表征.以四庚基溴化铵为相转移试剂将该系列杂多化合物转移至有机溶剂苯中,通过变温广角X-ray衍射及偏光显微镜研究了其在苯溶液中的结晶形态.
series tungstophosphate heteropoly compounds, Na 16 P 4W 30 M 4(H 2O) 2O 112 ·XH 2O(M=Sn 2+ ,Cd 2+ ),have been firstly synthesized and characterized by elemental analysis, IR, UV and 183 W NMR. With the aid of phase tranfer agent (tetraheptylammonium bromide), the heteropoly compounds are transferred to organic solvent(benzene). Their crystalline state in benzene are examined by various-temperature wide angle X-ray diffraction and polarized microscope.
