Abstract: | AbstractFive 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. |
