合成了新型邻菲咯啉镁(II)配合物 [Mg(H2O)4(phen)](phen)[C6H4(COO)2]?H2O, 并对其进行了元素分析、IR、TG、X-射线衍射等表征。单晶衍射结果表明, 该配合物晶体属单斜晶系, 空间群为 P21/c, 晶胞参数:a = 11.873(2), b = 31.992(6), c = 8.144(2) ?, β = 93.98(3), V = 3085.9(11)?3, Z = 4, F(000) = 1336, Dc = 1.375 g/cm3, μ(MoKα) = 0.120 mm?1。对于 6889[ Rint = 0.0264]个独立衍射点, 有 3939 个可观测点满足(I≥2σ (I)), 最终的偏离因子 R = 0.0430, wR = 0.1294。标题配合物由 1 个邻菲咯啉合镁阳离子[Mg(H2O)4(phen)]2+、1 个邻苯二甲酸根阴离子C6H4(COO)2)2–、1 个溶剂邻菲咯啉分子和 1 个结晶水分子组成。中心 Mg(II)离子为六配位, 六个配位原子形成畸变的 MgN2O4八面体构型。
A new type of phenanthroline magnesium (II) complex [Mg (H2O) 4 (phen)] (phen) [C6H4 (COO) 2] H2O has been synthesized and characterized by elemental analysis, IR, TG, X- Ray diffraction characterization. The results of single crystal diffraction show that the crystal of the complex belongs to the monoclinic system with a space group of P21 / c with unit cell parameters of a = 11.873 (2), b = 31.992 (6) and c = 8.144 = 93.98 (3), V = 3085.9 (11)? 3, Z = 4, F (000) = 1336, Dc = 1.375 g / cm3, μ (MoKα) = 0.120 mm? For the 6889 [Rint = 0.0264] independent diffraction points, 3939 observable points are satisfied (I≥2σ (I)), and the final deviation factor R = 0.0430 and wR = 0.1294. The title complex consisted of one ortho-phenanthroline magnesium cation [Mg (H2O) 4 (phen)] 2 +, one phthalate anion C6H4 (COO) 2) 2-, Molecule and a crystal water molecule. The central Mg (II) ions are hexacoordinated and the six coordination atoms form a distorted MgN2O4 octahedral configuration.
