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)]n(1)(mip=2-(3-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline,NDC=naphthalene-1,4-dicarboxylic acid),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=1.245 80(7)nm,b=1.474 50(9)nm,c=1.365 44(8)nm,β=97.644 0(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。
In this paper, a two-dimensional Mn (Ⅱ) complex [Mn (mip) (nC)] n (1) was synthesized by hydrothermal method using dicarboxylic acid and nitrogen- = 2 - (3-methoxyphenyl) -1H-imidazo [4,5-f] [1,10] phenanthroline, NDC = naphthalene-1,4-dicarboxylic acid, and its elemental analysis, infrared spectroscopy, Weight loss analysis, UV-Vis spectroscopy and X-ray single crystal diffraction characterization. The complex 1 belongs to the monoclinic system of P21 / n with the unit cell parameters of a = 1.245 80 (7) nm, b = 1.474 50 (9) nm, c = 1.365 44 0 (1) °. In 1, metallic manganese (II) coordinates with four O atoms from three NDC ligands and two N atoms from one mip ligand to form a distorted octahedral configuration. Complex 1 presents a two-dimensional (4,4) topological configuration. Thermogravimetric analysis shows that the decomposition of complex 1 has gone through two stages, and the structure of the complex is relatively stable. We have initially studied the fluorescence properties of the ligand and the complex 1, the results show that the complex 1 can be used as a potential luminescent material.
