摘要
摘要 1,4,7-三甲基-1,4,7-三氮杂环壬烷与氯化钐、氯化钆和氯化铽四氢呋喃盐反应生成单核络合物 [LnCl3(Me3tacn)(THF)n]（Me3tacn = 1,4,7-三甲基-1,4,7-三氮杂环壬烷；Ln = Sm (I)、Gd (II)，n = 1；Ln = Tb (III)，n = 0）。用 1,2,4-三苯基环戊二烯钾处理络合物 I 或 II 会产生单（环戊二烯）共络合物 [CpPh3LnCl2(Me3tacn)]（CpPh3 = 1,2,4-三苯基环戊二烯；Ln = Sm (IV)，Gd (V)）。即使使用两倍过量的 CpPh3K，也能形成络合物 IV 和 V。通过 X 射线衍射分析确定了 I-V 复合物的分子结构（CCDC 编号：2299485 (I)、2299487 (II)、2299486 (III)、2305352 (IV)、2306051 (V)）。
Lanthanide Complexes with 1,4,7-Trimethyl-1,4,7-triazacyclononane
The reaction of 1,4,7-trimethyl-1,4,7-triazacyclononane with samarium, gadolinium, and terbium chloride tetrahydrofuranates gives mononuclear complexes [LnCl3(Me3tacn)(THF)n] (Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane; Ln = Sm (I), Gd (II), n = 1; Ln = Tb (III), n = 0). The treatment of complexes I or II with 1,2,4-triphenylcyclopentadienyl potassium affords mono(cyclopentadienyl) co-mplexes [CpPh3LnCl2(Me3tacn)] (CpPh3 = 1,2,4-triphenylcyclopentadienyl; Ln = Sm (IV), Gd (V)). Complexes IV and V are formed even when a twofold excess of CpPh3K is used. The molecular structure of complexes I–V was established by X-ray diffraction analysis (CCDC nos. 2299485 (I), 2299487 (II), 2299486 (III), 2305352 (IV), 2306051 (V)).
