【摘要】 通过水热反应制备了二维配位聚合物[Mn(NAA)2(H2O)2]n(1)(HNAA=α-萘乙酸),采用元素分析、红外光谱、热重和单晶X-射线衍射对其进行了表征。结果表明该晶体属于单斜晶系,C2/c空间群:a=3.713 3(5)nm,b=0.625 4(5)nm,c=0.889 7(5)nm;β=99.706(5)°,Z=4。Mn原子与6个氧原子配位,形成八面体的配位构型。Mn(Ⅱ)原子通过α-萘乙酸双齿桥联形成层状的(4,4)网络结构,层与层之间进一步通过C-H...O和C-H...π相互作用形成三维超分子结构。同时研究了该配合物的热稳定性,荧光性质和抑菌活性。更多还原

【Abstract】 The two-dimensional coordination polymer,[Mn(NAA)2(H2O)2]n(1)(HNAA=α-naphthylacetic acid) has been synthesized and characterized by single-crystal X-ray diffraction studies,elemental analysis and FTIR spectrum.Structural determination reveals that it crystallizes in monoclinic space group C2/c.Crystal data:a=3.713 3(5) nm,b=0.625 4(5) nm,c=0.889 7(5) nm;β=99.706(5)°,Z=4.Each Mn(Ⅱ) atom is six-coordinated with a distorted octahedral geometry.The NAA-anion acts as a μ2-bridge linking Mn(Ⅱ) atoms generating a two-dimensional network with(4,4) topology,which are further bridged to form three-dimensional supramolecular structure by C-H…O hydrogen bonding and C-H…π interactions.The thermal stability,luminescence property and antibacterial activity of 1 were investigated.更多还原
