本文首次用吡嗪二甲酸为起始原料与二水氯化铜反应,合成了以吡嗪根为配体的单核铜(Ⅱ)配合物.对该配合物进行了元素分析表征,并对其进行了X-射线单晶结构测定.该单晶属于单斜晶系,空间群为P2(1)/c,其晶胞参数为a=3.8607(8)、α=90°,b=8.5731(17)、β=92.00(3)°,c=16.997(3)、γ=90°,V=562.2(2)3.在该配合物中每个吡嗪根提供一个氮原子配位于Cu(Ⅱ)离子而形成一平面,而两个氯原子分别配位于该四方形平面的上下方,形成矩形.
The mononuclear complex C8H8Cl2CuN4 with pyrazine and chlorine atom as ligands has been synthesized by Pyrazine-2,3-dicarboxylic acid and CuCl2.2H2O as starting materials at first time.The complex was characterized through elemental analysis and its crystal structure determined with X-ray crystallography.The crystal belongs to monoclinic system,space group P 2(1)/ c,with a = 3.860 7 (8) 、α = 90°,b = 8.573 1(17) 、β = 92.00(3)°,c = 16.997 (3) 、γ = 90°,V=562.2 (2) 3.In the complex the Cu (Ⅱ) ion was coordinated by two nitrogen atoms and two chlorine atoms,in which the two nitrogen atoms come from two pyrazine moleculars.The coordinated environment of the Cu(Ⅱ) is a rectangular.
