由H2pdc、phen、MnO2和H2O的水热反应体系合成了一种新型聚合物配合物[Mn(phen)(pdc)]∞(phen=1,10-菲咯啉，H2pdc=2,5-吡啶二甲酸)。 [Mn(phen)(pdc)]∞是由pdc桥接的边缘共享双核MnII结构单元的特征，导致其堆叠基于弱氢键相互作用的二维框架。 [Mn(phen)(pdc)]∞ 磁化率的温度依赖性表明相邻顺磁 MnII 离子之间存在反铁磁耦合 [J= −2.76(4) cm−1]。
A novel polymeric complex, [Mn(phen)(pdc)]∞(phen=1,10-phenanthroline, H2pdc=2,5-pyridinedicarboxylic acid) has been synthesized from the hydrothermal reaction system of H2pdc, phen, MnO2, and H2O. [Mn(phen)(pdc)]∞is characteristic of an edge-sharing dinuclear MnIIstructure unit bridged by pdc, leading to a 2-D framework whose stacking is based on weak H-bond interaction. The temperature dependence of the magnetic susceptibility for [Mn(phen)(pdc)]∞indicates antiferromagnetic coupling [J= −2.76(4) cm−1] between the adjacent paramagnetic MnIIions.
