以同物质的量比例的4-二苯基乙酸(Hbpa)、1,3-二(4-吡啶基)丙烷(bpp)和[Ag(NH3)](OH),在不同反应条件下制备了2个基于柔性配体的类三明治配合物{[Ag2(bpa)2(bpp)2]·2H2O}n(1)和{[Ag(bpa)(bpp)]·2H2O}n(2),对其进行了单晶结构、元素分析、红外光谱、荧光光谱和粉末衍射表征。结构表明1是由T型配位的银离子和Ag…Ag超分子作用组装而成的二维配合物;配合物2则是由四面体构型银离子和π…π堆积作用组装的二维配位超分子。此外,1和2还可在可见光区的不同位置发射较强荧光。
Prepared under different reaction conditions with 4-diphenylacetic acid (Hbpa), 1,3-bis (4-pyridyl) propane (bpp) and [Ag (NH3)] (OH) Two flexible ligand-based sandwich-like complexes {[Ag2 (bpa) 2 (bpp) 2] · 2H2O} n (1) and {[Ag (bpa) (bpp)] · 2H2O} n It was characterized by single crystal structure, elemental analysis, infrared spectroscopy, fluorescence spectroscopy and powder diffraction. The structure shows that 1 is a two-dimensional complex composed of T-coordinated silver ions and Ag ... Ag supramolecules. Complex 2 is a two-dimensional (2D) complex assembled by tetrahedral silver ion and π ... π stacking Coordination supramolecules. In addition, 1 and 2 can also emit strong fluorescence at different positions in the visible region.
