新型草酰胺大环Cu-Mn-Cu三核配合物的合成及其晶体结构

摘要

A novel oxamido-bridged macrocyclic trinuclear metal complex[CuL(DMF)]2Mn(SCN)2(1) was synthesized by diffusion reaction, using oxamido-bridged ligand CuL(H2L=2,3-dioxo-5,6 ∶13,14-dibenzo-9,10-(O)cyclohexyl-1,4,8,11-tetraazacyclo-tetradeca-7,12-diene) as coordination precursor, KSCN as ancillary ligand and Mn(ClO4)2·6H2O as metal core.The structure was characterized by UV-Vis, IR, elemental analysis, X-ray powder diffraction and X-ray single-crystal diffraction.The results indicated that 1(CCDC: 1535442) belongs to triclinic system and space group P-1 with cell parameters of a=9.951 0(19) , b=11.188(2) , c=13.907(3) , α=69.960(3)°, β=83.727(4)°, γ=63.665(3)°, V=1 301.9(4) 3, Z=1.%以草酰胺桥基配合物CuL(H2L=2,3-二氧-5,6 ∶13,14-二联苯基-9,10-环己基-1,4,8,11-四氮杂十四环-7,12-二烯烃)为前驱体,KSCN为辅助配体,Mn(ClO4)2为金属核心,经扩散反应合成了一种新型的大环三核金属配合物[CuL(DMF)2]2Mn(SCN)2(1),其结构经UV-Vis, IR,元素分析,X-射线粉末衍射和X-射线单晶衍射表征.结果表明:1(CCDC: 1535442)属三斜晶系,空间群P-1,晶胞参数a=9.951 0(19) , b=11.188(2) , c=13.907(3) , α=69.960(3)o, β=83.727(4)o, γ=63.665(3)o, V=1 301.9(4) 3, Z=1.
