18-冠-6与Na2[M(mnt)2](M=Cu,Ni)配合物的合成与结构 总被引:6,自引:0,他引:6
研究了18-冠-6分别与Na2[M(mnt)2][M=Cu,Ni;mnt=丁二腈烯二硫醇阴离子,C2S2(CN)^2^-~2]的反应,得到的配合物{[Na(18-C-6)][Na(18-C-6)(H2O)]}[Cu(mnt)2](1),[Na(18-C-6)(H2O)]2[Ni(mnt)2].(18-C-6)(2)通过元素分析、红外光谱、X射线单晶衍射进行了表征。两个配合物均为三斜晶系,空间群P1。1的晶体学结构数据:a=1.22697(19)nm,b=1.22780(19)nm,c=1.5665(3)nm,α=95.083(3)°,β=101.534(3)°,Υ=91.007(3)°,V=2.3016(6)nm^3,Z=2,Dcalcd=1.350g/cm^3,F(000)=976,R1=0.0726,wR2=0.1843.2的晶体学结构数据:a=1.11620(17)nm,b=1.22054(18)nm,c=1.27939(18)nm,α=111.647(2)°,β=29.792(3)°,Υ=103.201(2)°,V=2.5461(4)nm^3,Z=1,Dcalcd=1.304g/cm^3,F(000)=642,R1=0.0459,wR2=0.1003.1中的[Cu(mnt)2]^2^-通过mnt的氮原子与[Na(18-C-6)]^+中的钠原子成键,形成了一维链状结构;[Na(18-C-6)(H2O)]^+只起平衡电荷的作用。2中的[Ni(mnt)2]^2^-也通过配体的mnt氮原子与两个[Na(18-C-6)(H2O)]^+中的钠原子成键,形成稳定的中性配合物。 相似文献

Introduction Recently, many novel polymers with a variety of metal ions have been prepared and structurally characterized owing to the versatility of carboxylate ligands.1-5 Much attention has been devoted to this field partly because polymers of carboxylate ligands are good candidates for the investigation of exchange-coupling interactions between adjacent metal ions. A successful strategy to synthesize these complexes is the reaction of metal salts with properly selected multi-dentate carbox… 相似文献
