摘要 以偏钒酸、大环草酰胺配合物CuL(L=2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-diene)为共配体,利用液液扩散法设计并合成了有机-无机杂化杂金属多核配合物[Cd2(CuL)4(V4O12)].2CH3OH.2H2O(1).通过元素分析、红外光谱及X射线单晶衍射等方法进行了结构表征.结果表明:该配合物属于三斜晶系,P-1空间群;晶胞参数a=1.048 48(17)nm,b=1.331 7(2)nm,c=1.603 0(3)nm,α=93.662(2)°,β=104.084(2)°,γ=107.987(2)°,V=2.041 3(6)nm3,Z=1.其结构为通过大环草酰胺、V4O412-的配位作用构成的中心反对称的十核杂三金属Cd2Cu4V4配合物. The novel heterometallic complex [Cd2 (CuL)4 (V4O12)]·2CH3OH·2H2O(1) was synthesized by using the slow diffusion method with macrocylic oxamide and polyoxovanadate, and structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. For(1), the crystals crystallize in the triclinic system, space group P-1,a=1. 048 48 (17) nm,b= 1. 331 7(2) nm,c=1. 603 0(3) nm,a=93. 662(2)°,β=104. 084(2)°,7=107. 987(2)°,V=2. 041 3(6) nm3, Z=1. Complex (1)is a decadenuclear [Cd2Cu4V4 ] molecule via the oxamide and polyoxovanadate bridges.
