合成并表征了一个新的二维异核金属配位高分子Nd2 Zn3(EDTA ) 2 (H2 O ) 11·12H2 O。每个Nd3+离子通过 3个羧酸桥联 3个不同的Zn2 +离子 ,而每个Zn2 +连接两个Nd3+,组成 1个含有 6个稀土离子及 6个过渡金属的大环 ,环联在一起形成 1个二维的层。层间进一步由氢键联成三维网络。
A new two-dimensional heteronuclear metal coordination polymer Nd2 Zn3 (EDTA) 2 (H 2 O) 11 · 12H2O was synthesized and characterized. Each Nd3 + ion bridges three different Zn2 + ions through three carboxylic acids, and each Zn2 + connects two Nd3 + to form a macrocycle containing six rare earth ions and six transition metals, which are linked together Form a two-dimensional layer. The layers are further hydrogen bonded into a three-dimensional network.
