摘要
用水热法合成了离子型配合物[Ni(phen)2(CO3)].7H2O(1,phen=1,10-邻菲啰啉),其结构经IR和元素分析表征。X-射线单晶衍射分析表明,1属单斜晶系,P21/c空间群,晶胞参数a=0.989 97(8)nm,b=2.637 60(2)nm,c=1.058 43(9)nm,β=105.917(2)°,V=2.657 8(4)nm3,Z=4,Dc=1.513 g.cm-3,F(000)=1 004,μ=0.795 mm-1,R1=0.050 1,wR2=0.110 4。相邻的1中结晶水和配位的碳酸根通过O-H┈O和C-O┈H构成三维超分子氢键网络。在水溶液中测试了1的电化学性质,循环伏安法表明1具有较好的电化学性质,存在一对氧化还原峰,其峰电位分别为0.31 V和-0.40 V。
The three-dimensional water network complex,[Ni（phen）2（CO3）]·7H2O（1,phen=1,10-phenanthroline）,were synthesized by hydrothermal synthesis.The structure was characterized by IR and elemental analysis.X-ray diffraction analysis showed that 1 belongs to monoclinic system,space group P21/c with a=0.989 97（8） nm,b=2.637 60（2） nm,c=1.058 43（9） nm,β=105.917（2）°,V=2.657 8（4） nm3,Dc=1.513 g·cm-3,F（000）=1 004,Z=4,μ=0.795 mm-1,R1=0.050 1,wR2=0.110 4.In the crystal structure of 1,coordinated carboxyl and solvent water molecules are linked by intermolecular weak O-H┈O and C-H┈O hydrogen bonds lead to 3D network supramolecular complex.The electrochemical property of 1 in water was investigated by cyclic voltammetry.The results showed that 1 exhibited two redox waves at 0.31 V and-0.40.
