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。
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. CCDC: 847386.
