| 摘要: 利用柔性配体合成了配合物[Mn(pda)(bpp)] (1)(H2pda=1, 3-phenylenediacetic acid, bpp=1, 3-bi(4-pyridyl)propane), 并对其进行了元素分析、红外光谱和X 射线单晶衍射测定。配合物1属于正交晶系, 空间群为Pnna, a=1.965 2(6) nm, b=1.103 3(4) nm, c=0.963 9(3) nm, α=β=γ=90.0?, V=2.089 8(12) nm3, Z=4, Dc=1.416 Mg·m-3, μ=0.664 mm-1, F(000)=924, R1=0.040 2, wR2=0.133 2 (I>2σ(I))。配合物1的结构单元由1个MnⅡ、1个1, 3-pda和1个bpp构成。bpp交替连接MnⅡ形成1D右手螺旋链, 进一步通过1, 3-pda的连接构成2D螺旋层。从c轴方向看, 发现1DZ字链构成2D(4, 4)网格结构。同时还研究了配合物的热稳定性和电化学性质。 |

| Abstract: A coordination polymer of MnⅡ with flexible ligands, namely [Mn(pda)(bpp)] (1) (H2pda=1,3-phenyl-enediacetic acid, bpp=1,3-bi(4-pyridyl)propane), was synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. The results of structure characterization indicate that the complex crystallizes in the orthorhombic space group Pnna with a=1.965 2(6) nm, b=1.103 3(4) nm, c=0.963 9(3) nm, α=β=γ=90.0?, V=2.089 8(12) nm3, Z=4, Dc=1.416 Mg·m-3, μ=0.664 mm-1, F(000)=924, and final R1=0.040 2, wR2=0.133 2. The crystal structure of complex 1 consists of one MnⅡ, one 1,3-pda ligand and one bpp ligand. The bpp ligands bridge the MnⅡ ions to form a one-dimensional(1D) right-handed helical chain along the crystallographic b direction. Moreover, these helical chains are united together through the 1,3-pda ligands to afford a two-dimensional(2D) helical layer. Further investigation of this 2D structure suggests that the MnⅡ centers are connected to each other by bpp to afford a 1D zigzag chain along the crystallographic c direction. The 1D zigzag chains are interlinked by the 1,3-pda anions, constituting step-shaped 2D (4,4) network. In addition, thermal stability and electrochemistry of 1 have also been studied. CCDC: 885051. |
