摘要: 本文采取水热合成方法,利用二元羧酸和含氮杂环配体作为混合配体设计合成了一个二维Mn(Ⅱ)配合物[Mn(mip)(NDC)]n1)(mip=2-(3-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline,NDC=naphthalene-1,4-dicarboxylicacid),并对其进行元素分析、红外光谱分析、热失重分析、紫外-可见光谱分析和X-射线单晶衍射表征。配合物1属于单斜晶系,P21/n群,其晶胞参数如下:a=1.24580(7)nm,b=1.47450(9)nm,c=1.36544(8)nm,β=97.6440(1)°。在1中,金属锰(Ⅱ)与来自3个NDC配体的4个O原子和来自1个mip配体的2个N原子配位,形成扭曲的八面体构型。配合物1呈现二维(4,4)拓扑构型。热重分析表明配合物1的分解经历了两个阶段,并且该配合物的结构是比较稳定的。我们初步研究了配体和配合物1的荧光性能,结果表明配合物1可以做为潜在的发光材料。

Abstract: One coordination complex constructed from dicarboxylate acid and N-heterocyclic ligand as mixed ligands, namely, [Mn(mip)(NDC)]n (1) (mip=2-(3-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, NDC= naphthalene-1,4-dicarboxylic acid) has been synthesized by hydrothermal reaction. Complex 1 was characterized by elemental analysis, infrared spectrum (IR), single crystal X-ray diffraction, UV-Vis spectrum, and thermogravimetric analysis (TGA). Complex 1 crystallizes in monoclinic, space group P21/n with a=1.24580(7) nm, b=1.47450(9) nm, c=1.36544(8) nm, β=97.6440(1)°. In1, the metal ions Mn(Ⅱ) act as distorted octahedral geometry, being surrounded by four carboxylate oxygen atoms from three NDC ligands and two donor nitrogen atoms from one mip molecule. Complex 1 shows 2D (4,4) sheet topology. TGanalysis shows two clear courses of weight loss, which corresponds to the decomposition of different ligands. The structure-related solid-state uorescence spectra of free ligands and complex 1 have been determined, and the result displays that complex 1 should be acted as potential luminescent material.
