摘要
以反式4-[4′-(N,N-二甲胺基)苯乙烯基]-N-羧乙基吡啶盐(L)和叠氮化钠为配体,采用扩散法合成一种新型配位聚合物[Cd(N3)2(L)]n(1).单晶结构分析表明,配合物1属于正交晶系,P212121空间群.晶胞参数:a=6.719 0(6),b=8.102 1(7),c=35.050 2(18),Z=4,F(000)=960.配合物1中,Cd(II)离子与来自四个叠氮离子的氮原子以及两个L分子的氧原子配位,处于变形八面体环境中.相邻的Cd(II)离子被羧基/双叠氮三重桥联,形成一维链状结构.
A novel coordination polymer[Cd(N3)2(L)]n(L=trans4[(p-N,N dimethylamino)styryl]N acetic acid pyridinium)(1)has been synthesized with trans-4-[(p-N,N-dimethylamino)styryl]-N-acetic-acid pyridinium and NaN3as ligands.The crystal belongs to the orthorhombic system,space group P212121,with a=6.7190(6),b=8.1021(7),c=35.0502(18),Z=4,and F(000)=960.In complex1,the Cd(II)ion locates in a distorted octahedral geometry defined by four N atoms from four azido groups and two O atoms from two L ligands.The adjacent Cd(II)ions are further bridged via two azido groups and one carboxylate group,forming an one dimensional chain along the a axis.
