摘要
合成了标题配合物[Mn(phen)(H2O)4].SO4.2H2O,并对其进行了元素分析、红外光谱、紫外光谱等研究.X射线单晶衍射研究表明该配合物属正交晶系,空间群Pbca;晶胞参数:a=8.880 7(6)nm,b=18.517 3(12)nm,c=22.115 4(14)nm,β=90,°V=3 636.84 nm3,Z=8,密度Dc=1.605 mg/m3,吸收校正μ=0.895 mm-1,F(000)=1 816,测量温度为T=298(2)K,最终偏差因子分别为R1=0.046 7和ωR2=0.131 1.晶体结构表明,每个Mn(II)原子与来自邻二氮菲的2个氮原子和4个溶剂水分子的氧原子配位,形成畸变的八面体结构.该配合物通过分子间的弱相互作用形成了一个三维网状结构.
The complex [Mn（phen）（H2O）4]·SO4·2H2O is synthesized in this study. It is then analyzed through elemental analysis, IR and UV spectra. It is shown through the single crystal X -ray diffraction study that the complex is orthorhombic, with space group Pbca. The parameters are： α = 8. 880 7（6）nm, b = 18. 517 3（12） nm, c =22. 115 4（ 14）nm, ,8 =90°, V =3 636. 84 nm3, Z = 8, Dc = 1. 605 mg/m^3,μ =0. 895 mm^-1, F（000） = 1 816, T=298（2）K, R1=0. 046 7 and ωR2 =0. 131 1. It is made clear by the crystal structure that each Mn（Ⅱ） atom is coordinated with two nitrogen atoms from phenanthroline and four oxygen atoms from solvate water molecules to furnish a distorted octahedral geometry. The complex forms a three - dimensional polymer through intermolecular weak interactions.
