多吡啶配体H2L[N,N’-二(3-甲基吡啶基)-2,6-吡啶二酰胺]与Cu(OAc)2.H2O反应合成了一种新型的四核铜配合物——[Cu4L2(N3)2(μ2-N3)2].CH3OH(1),其结构经IR,XRD和元素分析表征。1属单斜晶系,空间群C2/m,晶胞参数a=15.774(3),b=15.062(3),c=10.724(2),β=114.91(3)°,V=2 344.0(8)3,Z=4,Dc=1.736 mg.cm-3,μ=1.869 mm-1,R1=0.120 1,ωR2=0.298 4。1中四个金属铜原子通过两个L2-配体,四个N3-基团连接在一起,形成了一个新颖的四核铜结构。
A novel tetranuclear copper complex was synthesized from the polypyridine ligand H2L [N, N’-bis (3-methylpyridyl) -2,6-pyridinedicarboxamide] with Cu (OAc) - [Cu4L2 (N3) 2 (μ2-N3) 2] .CH3OH (1) whose structure was characterized by IR, XRD and elemental analysis. 1 is a monoclinic with a space group of C2 / m with a = 15.774 (3) 晶, b = 15.062 (3) and c = 10.724 2 344.0 (8) 3, Z = 4, Dc = 1.736 mg.cm-3, μ = 1.869 mm-1, R1 = 0.1201, ωR2 = 0.298 Four metal copper atoms in 4.1 are separated by two L2- Ligand, four N3-groups are linked together to form a novel tetranuclear copper structure.
