Structural and Spectral Studies of Cis Cadmium(Ⅱ), Manganese(Ⅱ) and Nickel(Ⅱ) Complexes Having 2-Thiophenimidazo[4,5-f ][1,10]phenanthroline and 2-(5-Bromothiophen)imidazo[4,5-f ][1,10]phenanthroline Ligands
【摘要】 本文报道了3个基于2-噻吩咪唑[4,5-f][1,10]菲啰啉(TIP)和2-(5-溴-2-噻吩)咪唑[4,5-f][1,10]菲啰啉(5-Br-TIP)的镉(Ⅱ)配合物1[cis-Cd(TIP)2(NO3)2]、锰(Ⅱ)配合物2[cis-Mn(5-Br-TIP)2Cl2]和镍(Ⅱ)配合物3[cis-Ni(TIP)2Cl(CH3OH)]Cl.CH3OH的合成、波谱和晶体结构表征。它们均为顺式1∶2单核配合物,其中1为8配位,2和3为6配位,TIP和5-Br-TIP配体在不同配合物中噻吩和邻菲啰啉并咪唑环之间的二面角有所不同,但都不大,在3.9(1)°~9.2(1)°范围。
【Abstract】 Three mononuclear cadmium(Ⅱ),manganese(Ⅱ) and nickel(Ⅱ) complexes having 2-thiophenimidazo[4,5-f ] [1,10]phenanthroline(TIP) and 2-(5-bromothiophen)imidazo [4,5-f ] [1,10]phenanthroline(5-Br-TIP) ligands formulated as [cis-Cd(NO3)(TIP)2](1),[cis-MnCl2(5-Br-TIP)2](2) and [cis-NiCl2(TIP)2](3),have been synthesized and structurally compared.They are characterized by elemental analysis,FT-IR,UV-Vis spectra,luminescence spectra and X-ray single-crystal structural analysis.All of them are 1∶2 mononuclear complexes with the same cis configuration,among which complex 1 is eight-coordinated and the others are six-coordinated.Ligands TIP and 5-Br-TIP in complex 1~3 are essentially planar with the dihedral angles between imidazole and thiophene rings in the range of 3.9(1)°~9.2(1)°.CCDC: 922633,1;922634,2;922635,3.
