| 摘 要： | 嘧啶衍生物乳清酸作为一种生物小分子较少应用到金属-有机配合物的合成中。我们应用乳清酸与过渡金属盐反应，通过溶剂热方法合成了3个新颖的配合物：{Cu（HOr）2]·2NH2（CH3）2}n（R-1）、Co2（HOr）2（bipy）（H2O）6]·2H2O（R-2）和{Ni2（HOr）2（1，3-dpp）2（H2O）2]Ni（HOr）（1，3-dpp）（H2O）]2·（1，3-dpp）·2H2O}n（R-3）（H3Or=orotic acid，bipy=4，4''-bipyridine，1，3-dpp=1，3-di（4-pyridyl）propane）。应用X射线单晶衍射、元素分析、红外衍射、热重分析等对配合物进行了结构分析和表征。X射线单晶衍射分析表明：R-1是具有2D层结构的单核配合物，R-2为简单的单分子配合物，R-3则是由层和链组成的复杂三明治结构。这3个配合物均能通过分子间的氢键作用连接成三维的框架结构。

| Abstract: | Orotic acid as a pyrimidine derivative was less studied in the synthesis of metal-organic complexes. In this article, reactions of orotic acid as ligand with transition metal salts under solvothermal conditions gave rise to three new complexes, namely {Cu(HOr)2]·2NH2(CH3)2}n (R-1),Co2(HOr)2(bipy)(H2O)6]·2H2O (R-2) and {Ni2(HOr)2 (1,3-dpp)2(H2O)2] Ni(HOr)(1,3-dpp)(H2O)]2·(1,3-dpp)·2H2O}n (R-3) (H3Or=orotic acid, bipy=4,4''-bipyridine, 1,3-dpp=1,3-di(4-pyridyl)propane). All the complexes have been structurally characterized by single-crystal X-ray diffraction analyses and characterized by elemental analysis, infrared spectra (IR) and thermogravimetric analysis (TGA). X-ray crystallography analysis reveals that R-1 is mononuclear complex with 2D sheet structure, R-2 is a simple monomolecular complex, and R-3 is a complicated sandwich structure containing layers and chains. All the complexes are linked to form 3D framework through intermolecular hydrogen bonding interaction. |
