|
摘要
通过水热合成法合成了铜-2, 6-吡啶二甲酸的配合物[Cu(2,6-pidic)(H_2O)_2]_2的单晶,配合物属P-1空间群,晶胞参数为a=0.469 92(2) nm、b=0.893 20(3) nm、c=1.030 36(6) nm。配合物分子互不连接,每个晶胞中含2个分子,中心铜离子为5配位。配合物的磁性质测试结果表明,中心铜离子间为反铁磁性作用。
Complex [Cu(2,6-pidic)(H_2O)_2]_2was synthesized to obtain monocrystals using the hydrothermal method, whose space group P-1. The crystallographic data shows that a=0.469 92(2) nm, b=0.893 20(3) nm, c=1.030 36(6) nm. Each structure cell contains two molecules, one of which is isolated from the other. Coordination number of the center copper ions is five. Complex magnetic susceptibility measurement confirmed the antiferromagnetic interactions between the Cu~(2+)ions.
