摘要
吡啶-2,6-二甲酸是一个非常有趣、灵活多变的刚性配体,曾有“万能配体”之美誉。它能与过渡、非过渡、内过渡和锕系金属离子形成稳定配合物.而且配位方式不拘一格。吡啶-2,6-二甲酸的另一重要意义在于它是生物体内具有生物活性的物质.它的衍生物、配合物在诸如立体化学、结构、磁性、光谱动力学和反应机理,以及配体的反应、生物化学模拟系统及分析化学等学科领域内都得到广泛的研究和应用。
A copper(Ⅱ) complex [Cu(CAM)(H2O)2], (CAM=4-hydroxypyridine-2,6-dicarboxylic acid), has been hydrothermally synthesized and characterized by elemental analysis, IR, and X-ray diffraction single crystal structure analysis. It belongs to triclinic system, with space group P1, a=0.783 3(3) nm, b=0.796 5(3) nm, c=0.798 6(3) nm, α=100.340(6)°,β=93.768(6)°,γ=109.348(5)°, V=0.458 3(3) nm3, Z=2. The copper(Ⅱ) ion is 5-coordinated and exhi bits a distorted square pyramidal coordination environment. The two coordinated aqueous molecules and the oxygen atoms from the ligand generate the intermolecular hydrogen bonds, which result in the 2D supramolecular network. CCDC: 227156.
