| 摘要: 在有机溶剂中,通过卤素取代的salamo型双肟配体H2L1（4，4'，6，6'-tetrachloro-2,2'-（ethylenediyldioxybis（nitrilomethylidyne））diphenol），H2L1（5-nitro-4'，6'-dichloro-2，2'-（ethylenedioxybis（azomethine））diphenol）和四水合乙酸锰（Ⅱ）反应，合成了2个锰（Ⅱ）配合物[Mn（L1）（H2O）2]（1）和[Mn（L2）（H2O）2]·0.37H2O（2），并通过元素分析、红外光谱、紫外-可见吸收光谱、单晶X射线衍射、荧光光谱和Hirshfeld表面分析对2个锰（Ⅱ）配合物进行了表征。X射线晶体学结果表明2个配合物中的锰（Ⅱ）原子都是六配位的，其中salamo型配体的N2O2占据平面位置，2个配位水分子占据轴向位置，形成了扭曲的八面体几何构型。由于存在较丰富的氢键相互作用，在配合物1和2中分别形成了无限的一维和二维超分子结构。 | |

| Abstract: Two manganese(Ⅱ) complexes[Mn(L1)(H2O)2] (1) and[Mn(L2)(H2O)2]·0.37H2O (2) were synthesized by the reactions of halogen-substituted salamo-type bisoxime ligands H2L1, H2L1 with manganese(Ⅱ) acetate tetrahydrate in organic solvents, and the two complexes were characterized by the means of elemental analyses, FT-IR, UV-visible absorption spectra, single-crystal X-ray diffractions, fluorescence spectra and Hirshfeld surfaces analyses. X-ray crystallography results indicated that the manganese(Ⅱ) ions in the two complexes are all six-coordinated, in which the N2O2 of the salamo-type ligand occupied the planar position, and two coordinated water molecules occupied the axial positions, forming distorted octahedral coordination geometries. Due to abundant hydrogen bonding interactions, infinite 1D and 2D supramolecular structures are formed in complexes 1 and 2, respectively. | |
