4′-(4-tolyl)-2,2′:6′,2″-terpyridine} reveal distorted octahedral coordination geometry of the platinum(IV) metal centers with bidentate coordination of the terpyridine ligands. Complexation of 1–3 with iodopentafluorobenzene (IPFB) afforded single-crystal structures of halogen bond (XB) complexes 1a–3a, in which the Pt-complexes act as bifunctional XB bond acceptor wherein the pendant pyridine nitrogen
合成了三种新的2,2':6',2''-吡啶吡啶类有机三碘合三甲基碘化铂(IV)络合物,并通过1 H NMR光谱,质谱,元素分析和单晶X射线衍射分析进行了表征。PTME的X射线晶体结构3 I(L)配合物1 - 3 L为1 = 4'-氯-2,2':6',2“ -三联吡啶,2 = 4' - (4-氰基苯基) -2,2':6',2 ''-吡啶,且3 = 4'-(4-甲苯基)-2,2':6',2''-吡啶}}显示出铂(IV)的扭曲八面体配位几何金属中心与二吡啶配体的双齿配位。络合1 - 3与碘五氟苯(IPFB)一起提供卤素键(XB)配合物1a - 3a的单晶结构,其中Pt配合物充当双功能XB键受体,其中吡啶氮原子侧基和铂结合的碘原子充当XB受体, IPFB的极化碘。此外,1与1,4-二碘四氟苯(DITFB)的络合提供了二聚XB络合物(1b)的单晶结构,其中卤素键通过两个1和DITFB的吡啶氮原子发
