硝酸铜与2-甲基-5-吡嗪羧酸在室温无菌条件下通过反应得到[Cu(C6H6N2O2)2(H2O)2]n.n[NO3].nH2O配位聚合物,X射线衍射分析表明,该配合物属单斜晶系,P 21/c空间群,晶胞参数为a=0.837 4(2)nm,b=1.623 1(5)nmc,=0.767 3(2)nm,α=90°,β=98.509(5)°,γ=90°。配合物中存在硝酸根抗衡阴离子,丰富了氢键的来源,更易形成超分子的聚合物。且在此配合物中,还存在未键合的N原子和含有孤对电子的O原子,可作为配合物的配体,进一步与其它金属作用形成混金配位聚合物。
The Cu (C6H6N2O2) 2 (H2O) 2] nn [NO3] .nH2O complex was obtained by reaction of copper nitrate with 2-methyl-5-pyrazinecarboxylic acid under aseptic conditions at room temperature. The results of X-ray diffraction , The complex belongs to the monoclinic space group P 21 / c with unit cell parameters of a = 0.837 4 (2) nm and b = 1.623 1 (5) nmc = 0.767 3 °, β = 98.509 (5) °, γ = 90 °. The complex exists nitrate counter anion, enriched the source of hydrogen bonds, more likely to form supramolecular polymer. And in this complex, there are unbonded N atoms and O atoms containing lone pairs of electrons, which can be used as the ligand of the complex, and further with other metals to form a mixed gold coordination polymer.
