| A Three-Interpenetrating Cobalt(Ⅱ) Coordination Polymer Based on 4,4′-Azodibenzoic acid and 4,4′-Bipyridine: Solvothermal Synthesis, Crystal Structure and Thermal Stability Properties |

| 摘要: 通过溶剂热方法合成了一个三重穿插的钴的配位聚合物，[Co(ADB)(H2ADB)(BPY)]·2CH4OH(H2ADB为4，4′-偶氮二苯甲酸，BPY为4，4′-联吡啶)，并通过元素分析、红外光谱、热分析和X射线单晶衍射对其进行了表征。晶体结构研究结果表明该配合物属单斜晶系，C2/c空间群。在配合物中，每个钴原子分别与4个羧酸配体上的4个氧原子和2个BPY分子的氮原子配位，形成扭曲八面体几何构型。相邻钴原子之间通过ADB2-、H2ADB和BPY相连形成二维网络结构。有意思的是，在分子中存在3个相互独立但结构相同的二维网状结构，形成三重贯穿。 |

| Abstract: A Co coordination polymer, [Co(ADB)(H2ADB)(BPY)]·2CH4OH (H2ADB=4,4′-azodibenzoic acid, BPY=4,4′-bipyridine), has been synthesized by solvothermal reaction and characterized by element analysis, IR spectra, TGA curve and single-crystal X-ray diffraction. The crystallographic data shows that the title complex crystallizes in monoclinic system, space group C2/c. Each Co(Ⅱ) is six-coordinated to four O atoms from two ADB2-, two H2ADB ligands, two nitrogen atoms from two BPY molecules and forms distorted octahedral coordination geometry. The Co2+ ions are interlinked by the ADB2-, H2ADB and BPY to yield 2D net. CCDC: 745404. |
