| 摘要: 合成并表征了3个配合物NiL (1),Cu2L2(2)和Zn2L2(3)(H2L=1,2-双(3,5-二甲基-4-乙氧羰基-吡咯-2-基)苯)。单晶衍射结果表明在配合物1中,脱质子配体用4个氮原子与金属Ni(Ⅱ)配位,中心金属离子为扭曲的平面正方形配位构型。而双核配合物2拥有双螺旋结构,每个配体桥联2个具有平面正方形配位构型的铜中心。推测配合物3和2的结构类似。此外还研究了配体和配合物的荧光性质。 |

| Abstract: Three complexes, NiL (1), Cu2L2(2) and Zn2L2(3) based on H2L (where H2L=1,2-bis(3,5-dimethyl-4-ethyloxy-carbonyl-pyrrol-2-yl-methyleneamino)benzene) were synthesized and characterized. The X-ray diffraction analyses results show that in complex 1, the deprotonated ligand uses all of its N atoms to bind to the Ni(Ⅱ) ion, which displays a distorted square planar geometry. However, the binuclear complex 2 possesses a double-stranded helical geometry, in which each Cu(Ⅱ) ion is also four-coordinated with an extremely distorted square-planar geometry. The proposed structure of complex 3 is similar as that of 2. In addition, the fluorescence properties of all compounds are investigated in detail. |
