【摘要】 合成了1-甲基-1,4,7,10-四氮杂环十二烷（L）配体。在乙腈中培养了La（L）（CH₃CN）-（H₂O）（CF₃SO₃）₃配合物单晶,测定了其红外光谱和质子核磁共振谱。用X射线衍射方法测定了配合物的晶体结构,该晶体属于单斜晶系,P2₁/n空间群,a=0.9700（2）nm,b=1.5966（2）nm,c=1.9085（1）nm,β=104.71（3）°,V=2.8588（50）nm³。配合物中镧为9配位,其配位多面体为扭曲的单帽四方反棱柱体。更多还原

【Abstract】 The complex [La (L) (CH3CN) (H2O) (CF3SO3)3] was synthesized, where L = 1-methyl-1,4,7,10-tetraazacyclododecane. The crystal structure of the complex was determined and a final R value of 0. 060 and Rw value of 0. 064 were obtained, respectively. The crystal belongs to a monoclinic system, space group is P21/n with a=0. 9700(2) nm, 6=1. 5966(2) nm, c = 1. 9085(1) nm, β= 104. 71(3)°, V = 2. 8588(50) nm3, Z = 4, Dcalc=1. 93 g/cm3. The coordination number of lanthanum ion is nine, forming a distorted monocapped square antipriosm.更多还原
