19-trithia[3.3.3]pyridinophane (10) and its complexes with NiII, PdII, CuI, AgI and HgII were synthesised and their crystal structures were determined. The NiII and HgII complexes (11, 12) are mononuclear with 10 serving as an unusual quinquedentate ligand. The CuI complex 13 is also mononuclear with 10 being tetra-coordinated to a tetrahedral CuI. Palladium(II) forms a binuclear complex 14 which exists as an
合成了含吡啶的氮杂-硫杂大环3,11,19-trithia[3.3.3]pyridinophane (10)及其与NiII、PdII、CuI、AgI和HgII的配合物,并确定了它们的晶体结构。NiII 和 HgII 复合物 (11, 12) 是单核的,其中 10 作为不寻常的五齿配体。CuI 配合物 13 也是单核的,其中 10 四配位为四面体 CuI。钯 (II) 形成双核络合物 14,其以无机两性离子形式存在,两种 PdII 金属离子均采用预期的具有面配位的方形平面几何形状。银(I)与 10 形成一维配位聚合物(15 和 16),这些聚合物表现出两种不同的配位模式,即四面体和三角平面。发现大环10在一系列金属离子中没有表现出任何选择性。研究了几种配合物的电子和氧化还原特性。(© Wiley-VCH Verlag GmbH & Co.
