A new ditopic ligand, 4'-(4-(2,2,2-tris(1H-pyrazol-1-ido)ethoxymethyl)phenyl)-2,2':6',2''-terpyridine (pzt), has been prepared and its coordination chemistry studied. Metal ions with a preference for octahedral geometry form ML(2) complexes that are readily isolated and characterised, with the metal ion being bound to the terpyridine sites of both ligands. Other metal ions bind to the terpyridine site
一种新的双位配体4'-(4-(2,2,2-三(1H-吡唑-1-基)乙氧基甲基)苯基)-2,2':6',2''-吡啶(pzt)已制备并研究了其配位化学。具有八面体几何形状的金属离子形成ML(2)络合物,该络合物易于分离和表征,金属离子与两个配体的吡啶吡啶位点结合。其他金属离子仅与一个配体的三联吡啶位点结合。在银(i)的情况下,已分离出双核M(2)L(2)络合物,其中每个银离子与一个配体的叔吡啶位点和第二个配体的单个吡唑基供体基团配位。通过电喷雾质谱和NMR技术获得了金属离子与三(吡唑基)结合位点结合的证据。游离配体和三种金属配合物
