Synthesis and Crystal Structure of Mn(Ⅵ) Complexe with 3,3'-diformic-2,2'-dipyridine

以1,10-邻菲咯啉为原料,合成了标题化合物的配体(L),再以相同的原料,生成1,10-邻菲咯啉-5,6-二酮(D),D与KMnO4在碱性条件下,水-醇溶液中加热回流,得到标题配合物(B)。L及其配合物被元素分析、1H NMR和X-射线单晶衍射表征,结果表明:L属于正交晶系,Pbcn空间群,a=1.1091(3)nm,b=0.66174(15)nm,c=1.9168(4)nm.α=β=γ=90.00゜.B属于正交晶系,P21212空间群,a=1.37672(15)nm,b=0.63621(7)nm,c=0.83365(9)nm.α=β=γ=90.00゜,M n(Ⅵ)与4个H2O分子和两个配体羧酸的氧原子形成变形8面体。L-B:C C D C

The title compound （L） and it＇s Mn（Ⅵ） complexe（B） have been synthesized, they are all with the phenanthrene material. They have been characterized by elemental analysis, 1H NMR and X- ray crystal diffraction. Results show L and B the orthogonal system,L is Pbcn space group, a=1.1091（3）nm, b=0.66174（15）nm, c=1.9168（4）nm,α=β=γ= 90.00°. B is P21212 space group, a=1.37672（15）nm, b=0. 63621（7）nm, c=0.83365（9） nm.,α=β=γ=90.00° . Mn（Ⅵ） with the oxygen atoms of four water molecules and the oxygen atom of two carboxylic acid mole-ules is forming a tetragonally distorted octahedral structure. CCDC, L-B： 1420013-1420014.
