一维链状冠醚配合物:Na(18-C-6)2Zn(mnt)2的合成与晶体结构

摘要

The novel complex [Na(18-C-6)]2[Zn(mnt)2](1) was characterized by elemental analysis, IR spectrum and X-ray diffraction analysis. 1 beolngs to monoclinic,space group C2/c with cell dimensions:a=2. 241 8(6),b=1. 1359(3),c=1. 9887(6) nm , β=120. 391(4)',V=4.368(2) nm3,Z=4,Dcalcd=1.399g/cm3,F(000)=1920,wR1=0.0362,wR2=0.0560. The complex display an one-dimensional chain of [Na(18-C-6)]+complex cations and[Zn(mnt)2]2- complex anion bridged by Na-O interactions between adjacent[Na(18-C-6)]+units.%研究了18冠6与Na2[Zn(mnt)2]的反应,并通过元素分析、红外光谱、单晶X-射线衍射对生成的配合物[Na(18-C-6)]2[Zn(mnt)2]进行了表征.配合物为单斜晶系,空间群C2/c.晶体学数据:a=2.2418(6),b=1.1359(3),c=1.9887(6)nm,β=120.391(4)°,V=4.368(2)nm3,Z=4,Dcalcd=1.399g/cm3,F(000)=1 920,R1=0.0362,wR2=0.0560.在固态,配合物中,两个分子通过18冠6氧原子连接形成一维链状结构.
