摘要： 以K3Mn(CN)6,N,N-二甲基甲酰胺和Eu(NO3)3·6H2O为原料合成了新型一维链状氰根桥联配合物[Eu(DMF)4(H2O)2Mn(CN)6·H2O]n,并通过元素分析、红外光谱和紫外光谱进行了表征.利用单晶X射线四圆衍射测定了配合物的晶体结构,结果表明,晶体属单斜晶系,P21/c空间群,晶胞参数a=1.2992(3)nm,b=1.2764(3)nm,c=1.9154(4)nm,β=109.42(3)°,V=2.9956(12)nm3,Dx=1.573Mg/m3,Z=4,R=0.0372,Rw=0.0962,GOF=1.095.在Eu和Mn原子之间存在两个CN桥,配合物呈现一维链状结构.

Abstract: Using K3Mn(CN)6, N,N-dimethylformamide(DMF) and Eu(NO3)3·6H2Oas reactants, a novel one dimensional cyano bridged chain complex [Eu(DMF)4·(H2O)2Mn(CN)6·H2O]n has been first synthesized and characterized with elemental analysis, IR, UVspectra and X-ray crystal analysis. The complex crystallizes in the monoclinic P21/c space group, with lattice parameters a =1.2992(3) nm, b =1.2764(3) nm, c =1.9154(4) nm, β =109.42(3)°, V =2.9956(12) nm3, Dx=1.573 Mg/m3, Z =4, R =0.0372, Rw=0.0962, GOF=1.095. The complex shows one dimensional chain structure due to the two bridging CNbetween Eu and Mn atom.
