platinum(II) complexes of ligands incorporating three linked, 16-membered, N2S2-donor macrocycles, together with their single-ring analogues have been synthesised. The former complexes are of the form [M3L](PF6)6 (where M = Pd or Pt, and L is a linked three-ring macrocyclic species incorporating a 1,3,5-‘tribenzyl’ or a phloroglucinol core). The X-ray structure determination of the single ring species [PdL](PF6)2
合成了配体的钯(II)和铂(II)配合物,这些配合物结合了三个连接的,16元的N 2 S 2-供体大环以及它们的单环类似物。前一种配合物的形式为[M 3 L](PF 6)6(其中M = Pd或Pt,L是结合有1,3,5-'三苄基'或间苯三酚核心的三环大环物种)。单环物质[PdL](PF 6)2(其中L是N 2 S 2的单个N-苄基衍生物)的X射线结构测定-供体大环)显示钯以'正方形平面'方式与大环的所有四个供体原子配位。含三连接金属的物质的电喷雾质谱表明,由于六氟磷酸抗衡离子和氢的损失而产生了一系列多电荷离子,分别对应于[M- n PF 6 ] n +和[M- n PF 6 - 米H] (ñ - 米)+。单个带电峰的扩展揭示了由于存在三种金属离子而产生的预期宽质量范围,每种金属离子都具有许多同位素。分光光度滴定法证实,这些三联配体在乙腈中的配合物的化学计量比为3:1(金属:配体)。
