complexes containing substituted-2,2′:6′,2″-terpyridine ligands of [Ni II (pytpy) 2 ]Cl 2 . H 2 O (pytpy = 4′- (4-pyridyl)-2,2′:6′,2″-terpyridine) ( 1 ), [Pt(tpyOH)Cl] + Cl − . 2H 2 O ( 2 ) (tpyOH = 4′-hydroxy-2,2′:6′,2″-terpyridine) and [Pt(tpySH)Cl] + Cl − .2H 2 O ( 3 ) (tpySH = 4′-mercapto-2,2′:6′,2″-terpyridine) have been prepared.

摘要 三种新的d 8 过渡金属配合物含有[Ni II (pytpy) 2 ]Cl 2 的取代-2,2':6',2"-三联吡啶配体。H 2 O (pytpy = 4'-(4-吡啶基)-2,2':6',2"-三联吡啶) (1), [Pt(tpyOH)Cl] + Cl - 。2H 2 O ( 2 ) (tpyOH = 4'-羟基-2,2':6',2"-三联吡啶) 和 [Pt(tpySH)Cl] + Cl - .2H 2 O (3) (tpySH = 4' -mercapto-2,2':6',2"-terpyridine) 已制备。1的晶体结构表明,镍(II)由扭曲八面体几何形状NiN 6 中pytpy的六个氮原子六配位,而铂配合物( 2 )由一个Cl - 和三个氮原子四配位tpyOH 在扭曲的方形平面几何 PtClN 3 中。晶格结晶水分子在配合物1和2中起着重要的结构导向作用。许多强非共价相互作用存在于
