在水热条件下(120℃),醋酸铜,2,2′-联吡啶(bpy)与5-硝基间苯二甲酸(H2NIPH)反应72h,得到配位聚合物[Cu(NIPH)(bpy)](1).单晶X射线衍射分析表明,配位聚合物1具有类螺旋形链结构,链间通过弱共价键、氢键和π-π相互作用形成三维网络结构.晶体属于单斜晶系,P2(1)/c空间群,a=0.95510(19)nm,b=1.2592(3)nm,c=1.3737(3)nm,β=95.13(3)°,V=1.6455(6)nm3,Z=4,Mr=428.84,Dc=1.731Mg/m3,Z=4,R=0.0297,wR2=0.0979.热重分析表明,配位聚合物1具有良好的热稳定性.另外该配位聚合物显示了较强的反铁磁行为.
Under hydrothermal conditions (120 ℃), copper acetate, 2,2’-bipyridyl (bpy) and 5-nitroisophthalic acid (H2NIPH) were reacted for 72h to obtain the coordination polymer [Cu )] (1). Single crystal X-ray diffraction analysis showed that the coordination polymer 1 has a helical chain-like structure, the three-dimensional network structure formed by weak covalent bonds, hydrogen bonds and π-π interactions between the chains. A = 0.95510 (19) nm, b = 1.2592 (3) nm, c = 1.3737 (3) nm, β = 95.13 (3) ° and V = 1.6455 (6) ) nm3, Z = 4, Mr = 428.84, Dc = 1.731 Mg / m3, Z = 4, R = 0.0297, and wR2 = 0.0979. Thermogravimetric analysis showed that the coordination polymer 1 has good thermal stability. Biphasic polymers show strong antiferromagnetic behavior.
