Abstract Five new coordination complexes [MnII (L1)2(4,4′-bpy)]n (1), [NiII (L1)2(4,4′-bpy)]n (2), [ZnII (L1)2(4,4′-bpy)]n (3), [CuII (L1)2(phen)2]Cl2 (4) and [CuII 2(L1)2(2,2′-bpy)2]Cl2 (5) (HL1 = 3,4,5-trifluorobenzeneseleninic acid, 4,4′-bpy = 4,4′-bipyridine, 2,2′-bpy = 2,2′-bipyridine and phen = 1,10-phenanthroline), have been synthesized and characterized by single-crystal X-ray diffraction, powder X-ray diffraction (PXRD), elemental analysis and IR spectroscopy. Complexes 1–3 display similar layers structures. In 1–3, the adjacent layers are further connected through π···π interactions to form three-dimensional supramolecular structures. Complexes 4 and 5 show a dimer containing an eight-membered ring. The dimer extends into three-dimensional supramolecular structures through π···π interactions, C–H···F and C–H···Cl interactions.

基于 3,4,5-三氟苯硒酸和 N-供体配体的 Mn(II)、Ni(II)、Cu(II) 和 Zn(II) 配位配合物的合成、结构

摘要 五种新配位配合物 [MnII (L1)2(4,4'-bpy)]n (1), [NiII (L1)2(4,4'-bpy)]n (2), [ZnII (L1) 2(4,4'-bpy)]n (3), [CuII (L1)2(phen)2]Cl2 (4) 和 [CuII 2(L1)2(2,2'-bpy)2]Cl2 ( 5) (HL1 = 3,4,5-三氟苯硒酸，4,4'-bpy = 4,4'-联吡啶，2,2'-bpy = 2,2'-联吡啶和 phen = 1,10-菲咯啉) , 已合成并通过单晶 X 射线衍射、粉末 X 射线衍射 (PXRD)、元素分析和红外光谱表征。复合体 1-3 显示类似的层结构。在1-3中，相邻层通过π···π相互作用进一步连接，形成三维超分子结构。复合物 4 和 5 显示一个包含八元环的二聚体。二聚体通过π···π相互作用、C-H···F和C-H···Cl相互作用延伸到三维超分子结构中。
