草酰胺桥联异三核配合物Cu(NiL)2(ClO4)2的合成、光谱表征和晶体结构(英) 总被引:1,自引:0,他引:1
A novel oxamido-bridged trinuclear complex Cu(NiL)2(ClO4)2(where H2L=2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,3-dien) has been synthesized and characterized by elemental analysis, IR spectrum, UV-Visible spectrum and single crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n. The lattice parameters are: a=1.052 4(6) nm, b=1.182 1(6) nm, c=1.586 2(9) nm, β=91.657(9)°, and V=1.972 6(19) nm3, Z=2. The results show that the coordination geometry around copper(Ⅱ) in the title complex is hexa-coordinated octahedron. CCDC: 232608. 相似文献

A novel macrocyclic oxamide complex CuL (L=C33H28Cl2N4O3) has been synthesized and characterized by elemental analysis, IR spectrum, UV-Visible spectrum and single crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n. The lattice parameters are: a=0.848 8(3) nm, b=1.904 9(7) nm, c=1.868 1(7) nm, β=92.794 (6)° and V=3.016 8(19) nm3, Z=4. The results show that the coordination geometry around copper(Ⅱ) in the complex is aberrant tetragonal-plane. CCDC: 265601. 相似文献

合成了含有草酸根(OX)桥基的铁(Ⅲ)的配合物配体[Hpip] [(salen)FeⅢ(OX)](pip=哌啶;salen=N,N'-二水杨醛缩乙二胺),并解析了其晶体结构.利用这一含有草酸根桥基的配合物配体组装了3个新的异三核配合物[(salen)FeⅢ(μ-OX)]2[MⅡ(H2O)2]·nH2O[MⅡ=CuⅡ(1), NiⅡ(2),FeⅡ(3)],并进行了结构表征,变温磁化率(4.2~300 K)测定结果均未表现出非正规自旋态的类铁磁行为.通过计箅和分析,讨论了满足"非正规自旋态"的充分和必要条件> 相似文献
