| 摘要: 合成了2个新的基于双（salamo）型配体H4L的镍（Ⅱ）和锌（Ⅱ）配合物[Ni3（L）（μ-OAc）2（CH3OH）3]·CH3OH·0.25CHCl3（1）和[Zn3（L）（μ-OAc）2（CH3OH）（H2O）]·2CH3OH（2），并通过元素分析、红外光谱、紫外-可见吸收光谱、X射线单晶衍射、热稳定性（TGA）和Hirshfeld表面分析对其进行了结构表征。X射线晶体学分析表明：配合物1为非对称三核构型，其3个镍（Ⅱ）原子均为六配位，形成了一个稍微扭曲的八面体构型，而配合物2是一个对称的三核结构，中心的锌（Ⅱ）原子是六配位的，具有一种扭曲的八面体构型，与众不同的是另外2个锌（Ⅱ）原子是五配位的，表现为扭曲的三角双锥构型。此外，配合物1和21通过氢键和C-H…π相互作用形成了三维超分子结构。最特别的是，配合物1和2的荧光性质截然不同。 |

| Abstract: Two new homo-trinuclear Ni(Ⅱ) and Zn(Ⅱ) complexes,[Ni3(L)(μ-OAc)2(CH3OH)3]·CH3OH·0.25CHCl3 (1) and[Zn3(L)(μ-OAc)2(CH3OH) (H2O)]·2CH3OH (2) with a newly synthesized C-type bis(salamo)-like ligand H4L have been prepared and structurally characterized. The structures of complexes 1 and 2 were fully characterized by elemental analyses, FT-IR, UV-visible spectroscopy, single crystal X-ray crystallography, thermal analyses (TGA) and Hirshfeld surfaces analyses, and their luminescence properties were also discussed. The X-ray crystallography analyses demonstrated that complex 1 is an asymmetric trinuclear structure, and all Ni(Ⅱ) ions are hexa-coordinated, forming distorted octahedral geometries. Meanwhile, complex 2 is a symmetric trinuclear structure, the central Zn2 ion is hexa-coordinated and possesses a distorted octahedral coordination geometry. However, the terminal Zn1 and Zn1#1 ions are both penta-coordinated environments and adopt distorted trigonal bipyramidal geometries. In addition, 3D supramolecular architectures of complexes 1 and 2 were formed by hydrogen bonding and C-H…π interactions. Most importantly, the fluorescent property of complex 2 is totally different from that of complex 2. |
