Abstract Two new metal–organic coordination polymer frameworks formulated as, {[Co(nta)]·H 3 O + } n ( 1 ), and {[Zn(ina)Cl 2 ]·H 3 O + ·H 2 O} n ( 2 ) (nta = nitriliotriacetic acid, ina = isonicotinate), have been synthesized under mild conditions and characterized by elemental analyses, IR spectrum, PXRD, thermal gravimetric analysis (TG) and single-crystal X-ray diffraction. Complex 1 crystallizes in the orthorhombic space group P 2(1)2(1)2(1) with unit cell parameters a = 8.403(4) Å, b = 10.165(5) Å, c = 11.230 Å, β = 90, V = 959.3(9) Å 3 . Complex 2 crystallizes in the monoclinic space group P 2(1)/c with unit cell parameters a = 7.1334(13) Å, b = 22.369(4) Å, c = 7.0089(13) Å, β = 101.099(2), V = 1097.5(3) Å 3 . In fact, 1 is a new 3D cobalt complex with the nta ligands acted as bridges to form network polymer. Each nta ligand bonds to three cobalt ions, and each cobalt ion coordinates with three nta ligands in different directions. 2 displays a new 1D zigzag chain linked by ina ligand and an interesting 1D hydrogen-bond infinite chain consists of seven-membered rings and four-membered rings. These chains are further linked to generate a new 3D framework. Graphical Abstract Two novel metal–organic coordination polymer frameworks have been synthesized under mild conditions and characterized by elemental analyses, IR spectrum, PXRD, thermal gravimetric analysis (TG) and single-crystal X-ray diffraction.

摘要 两种新的金属-有机配位聚合物骨架，公式为 {[Co(nta)]·H 3 O + } n ( 1 ) 和 {[Zn(ina)Cl 2 ]·H 3 O + ·H 2 O} n ( 2 ) (nta = 次氮基三乙酸，ina = 异烟酸酯)，已在温和条件下合成，并通过元素分析、IR 光谱、PXRD、热重分析 (TG) 和单晶 X 射线衍射表征。配合物 1 在正交空间群 P 2(1)2(1)2(1) 中结晶，晶胞参数 a = 8.403(4) Å, b = 10.165(5) Å, c = 11.230 Å, β = 90, V = 959.3(9) Å 3 。配合物 2 在单斜空间群 P 2(1)/c 中结晶，晶胞参数 a = 7.1334(13) Å, b = 22.369(4) Å, c = 7.0089(13) Å, β = 101.099(2), V = 1097.5(3) Å 3 。事实上，1 是一种新的 3D 钴配合物，nta 配体充当桥梁以形成网络聚合物。每个nta配体与三个钴离子键合，每个钴离子与三个不同方向的nta配体配位。图 2 显示了一个由配体连接的新一维锯齿形链和一个有趣的一维氢键无限链，由七元环和四元环组成。这些链进一步链接以生成新的 3D 框架。图形摘要 在温和条件下合成了两种新型金属-有机配位聚合物骨架，并通过元素分析、红外光谱、PXRD、热重分析 (TG) 和单晶 X 射线衍射表征。这些链进一步链接以生成新的 3D 框架。图形摘要 在温和条件下合成了两种新型金属-有机配位聚合物骨架，并通过元素分析、红外光谱、PXRD、热重分析 (TG) 和单晶 X 射线衍射表征。这些链进一步链接以生成新的 3D 框架。图形摘要 在温和条件下合成了两种新型金属-有机配位聚合物骨架，并通过元素分析、红外光谱、PXRD、热重分析 (TG) 和单晶 X 射线衍射表征。
