5-bis(N,N-di(2-hydroxyethyl)iminomethyl)acridine (BHIA) with Ag(I), Cu(II) and Cd(II) were synthesized, characterized and investigated by the methods of single crystal X-ray diffraction, IR, and Raman spectroscopy. Single crystal X-ray analysis reveals that three different coordination manners of the BHIA occur. Five atoms of the BHIA molecule take part in the formation of complex with Ag(I) and six
摘要高选择性new啶基荧光团4,5-双(N,N-二(2-羟乙基)亚氨基甲基)ac啶(BHIA)与Ag(I),Cu(II)和Cd( II)通过单晶X射线衍射,IR和拉曼光谱法的方法合成,表征和研究。单晶X射线分析表明,BHIA发生了三种不同的配位方式。BHIA分子的五个原子参与与Ag(I)形成络合物,六个原子参与与Cu(II)形成络合物。在具有Cd(II)相互作用的BHIA情况下,阳离子的配位可能性取决于阴离子,从5到7不等。通过IR和拉曼光谱对BHIA配合物的研究表明,如果分子中有两个游离羟基,则振动光谱由许多旋转构象产生。BHIA分子与金属阳离子的不同结合方式最明显地表现在拉伸OH振动区域的红外光谱中。
