Organometallic monomeric and dimeric, neutral and cationic, κ2- and κ4-coordinated mono-pendant arm triazacyclononane complexes of aluminium and indium have been prepared, along with three new mono-pendant arm triazacyclononane ligand precursors HL4, HL5 and HL6 (HL4 = 1-(2-hydroxy-2-methylethyl)-4,7-diisopropyl-1,4,7-triazacyclononane; HL5 = 1-(2-hydroxy-2-methylethyl)-4,7-dimethyl-1,4,7-triazacyclononane;
有机金属单体和二聚体,中性和阳离子,κ 2 -和κ 4的铝和铟配位的单挂件臂氮杂环壬烷配合物已经制备,用三新单挂件臂沿三氮杂环壬烷 配体前体HL 4,HL 5和HL 6(HL 4 = 1-(2-羟基-2-甲基乙基)-4,7-二异丙基-1,4,7-三氮杂环壬烷; HL 5 = 1-(2-羟基-2 -甲基乙基)-4,7-二甲基-1,4,7-三氮杂环壬烷; HL 6 = 1-(2-羟基-2,2-二苯乙基)-4,7-二异丙基-1,4,7-三氮杂环壬烷)。HL 4或HL 5与AlMe 3或阿尔梅3 ·PY给出了μ-醇盐桥二聚的配合物[铝2(κ 2 -L 4)2我4 ]和[铝2(κ 2 -L 5)2我4 ]。HL 4与以下两个等价物的反应AlMe 3给人的单体化合物[铝(κ 2 -L 4 ·阿尔梅3)Me 2 ]也可通过处理[铝制备2(κ 2 -L 4)2我4 ]与2个当量的AlMe 3。HL的反应2与阿尔梅3
