analysis (TGA) and X-ray diffraction powder (PXRD) analysis. The structural analysis reveals that complex 1 exhibits a traditional 2-nodal (3,5)-63}69·8}-hms network, complex 2 shows a new 2D 63}65·8}, and complex 3 exhibits a novel 3D (3,4)-c pillar-layered architecture with a point symbol of 63}264.8.10}3. Furthermore, magnetic studies show that complexes 1 and 2 exhibit antiferromagnetic properties
三种新的配位聚合物(CP),配制成[Ni(HDCPN)(4,4'-bpy)(CH 3 CH 2 OH)(H 2 O)2 ]·0.5CH 3 CH 2 OH} n(1) ,[Ni 3(DCPN)2(4,4-bibp)4(H 2 O)4 ]·2CH 3 CH 2 OH·5H 2 O} n(2)和[Cu 3(DCPN)2( 1,3-bimb)3 ]·6H 2 O·2DMF} n(3)(H3 DCPN = 6-(3,5-二羧基苯基)烟酸和1,3-bimb = 1,3-双(咪唑-1-基甲基)苯,4,4'-bpy = 4,4'-联吡啶,4在水热条件下合成了4,4′-bibp = 4,4′-双(苯并咪唑-1-基)联苯。通过单晶X射线衍射分析,元素分析(EA),红外光谱,热重分析(TGA)和X射线衍射粉末(PXRD)分析对这些CP进行了深入研究。结构分析表明,复合物1表现出传统的2节点(3,5)-6
