摘要
利用水热合成方法制备了组成为[Cu(en)(H2O)(2,2′-bipy)]2H3BW12O4.02.5H2O的多金属氧簇有机-无机复合物,并用元素分析、IR和UV光谱、XPS、TG、荧光光谱、X射线单晶衍射对化合物进行了表征和性质研究.该化合物属于单斜晶系,P2(1)/c空间群,a=1.951 1(2)nm,b=1.229 76(12)nm,c=2.505 9(3)nm,β=91.266(2)°,V=6.011 1(11)nm3,Z=4.化合物阴离子[BW12O40]5-与配位阳离子[Cu(en)(H2O)(2,2′-bipy)]+通过静电作用相结合.XPS表明化合物中Cu、W氧化态分别为+1和+6价.
Organic-inorganic compound [Cu(en)(H2O)(2,2′-bipy)]2H3[BW12O40]·2.5H2O has been prepared under hydrothermal conditions and characterized by using elemental analysis,IR and UV spectrometry,XPS,TG,fluorescence spectrometry and X-ray single crystal diffraction analysis.The title compound crystallizes in monoclinic system,P2(1)/c space group,a=1.951 1(2) nm,b=1.229 76(12) nm,c=2.505 9(3) nm,β=91.266(2)°,V=6.011 1(11) nm3,Z=4.In the title compound,the heteropolyanion [BW12O40]5- combines the coordination cation [ Cu (en) ( H2 0 ) (2,2'-bipy) ]· through electrostatic interaction.
