A series of transition-metal complexes of N,N′,N″,N‴-tetra(3-hydroxypropyl)cyclam (L1) are reported. The X-ray structures of the compounds reveal pendant arm coordination of one of the alcohol groups to give square-pyramidal metal centres with simultaneous hydrogen bonding to the counter anions. Ligand L1 has been elaborated to form a series of macrotricyclic derivatives that form 1 ∶ 1 complexes with Cu(II) and Ni(II). The X-ray structure of the tetrahydrate and protonated forms of L1 are also reported.
报告了一系列 N,N′,N″,N‴-四(3-羟基丙基)环酰胺(L1)的过渡
金属配合物。这些化合物的 X 射线结构显示,其中一个醇基以垂臂配位方式形成方阵
金属中心,同时与反阴离子发生氢键作用。
配体 L1 被进一步加工成一系列大环衍
生物,与 Cu(II) 和 Ni(II) 形成 1 ∶ 1 复合物。此外,还报告了 L1 的四水合物和质子化形式的 X 射线结构。
