为进一步探索双核铜配合物的合成技术及结构特点,利用4-氟水杨酸(H2foac),1,10-邻菲罗啉(phen)与乙酸铜通过溶剂热合成方法合成了一个中心对称的双核铜配合物[Cu2(foac)2(phen)2]·10H2O,对其进行了X射线单晶衍射仪、元素分析、红外光谱、紫外-可见光谱等分析测试。该配合物属于三斜晶系,P1空间群,晶胞参数a=0.671 39(6)nm,b=1.149 23(11)nm,c=1.443 75(14)nm,α=72.640(9)°,β=76.857(8)°,γ=76.491(8)°。每个铜离子与2个配体foac的3个氧原子以及phen配体的2个氮原子配位形成四棱锥结构,通过分子间氢键作用构成一维链状结构,进一步利用分子间水簇作用构成了二维层状结构。
In order to further explore the synthesis technology and structural characteristics of the binuclear copper complex, a centrosymmetric structure was synthesized by solvothermal synthesis using 4-fluorosalicylic acid (H2foac), 1,10-phenanthroline (phen) and copper acetate Binuclear copper complex [Cu2 (foac) 2 (phen) 2] · 10H2O was prepared and characterized by X-ray single crystal diffraction, elemental analysis, infrared spectroscopy and UV-Vis spectroscopy. The complex belongs to triclinic system with P1 space group. The unit cell parameters a = 0.671 39 (6) nm, b = 1.149 23 (11) nm, c = 1.443 75 , β = 76.857 (8) °, γ = 76.491 (8) °. Each copper ion coordinates with three oxygen atoms of two ligands foac and two nitrogen atoms of phen ligand to form a pyramid structure, which forms a one-dimensional chain structure by intermolecular hydrogen bonding and further utilizes intermolecular water clusters The role constitutes a two-dimensional layered structure.
