praseodymium(III) and neodymium(III) complexes of heptadentate (N4O3) ligand trensal, tris[2-(salicylideneamino)ethyl]amine (H3L1), have been studied. These complexes (PrL1 and NdL1) were prepared by the reaction of the praseodymium(III) or neodymium(III) complex of 1,9-bis(2-aminoethyl)-1,4,6,9,12,14-hexaazacyclohexadecane with salicylaldehyde in acetonitrile. Alternatively, the reaction of tris(2-aminoethyl)amine
已经研究了七齿 (N4O3) 配体三 [2-(水杨基氨基)乙基]胺 (H3L1) 的镨 (III) 和钕 (III) 配合物的制备和表征。这些配合物(PrL1 和 NdL1)是通过 1,9-双(2-氨基乙基)-1,4,6,9,12,14-六氮杂环十六烷的镨(III)或钕(III)配合物与乙腈中的水杨醛。或者,三(2-氨基乙基)胺和水杨醛在镨(III)或钕(III)盐的存在下在乙腈中的反应也得到镨(III)和镨(III)配合物。PrL1和NdL1的分子结构通过X射线结构分析确定;这些是镧系元素七齿络合物的罕见例子,其中金属离子由四个氮原子和三个氧原子配位。Pr(C27H27N4O3)·0.5CH3CN和Nd(C27H27N4O3)·0.5CH3CN的晶体均为三角晶,空间群为a = 13.713(2), c = 8.093(3) A, U = 1318.0(7) A3 ..
