【摘要】 本文包括两部分内容,第一部分以三种过渡金属的氰根配合物K3[Fe(CN)6]、K4[Mo(CN)8]和K4[Fe(CN)6]作为配位前驱体,与过渡金属离子和稀土金属离子通过自组装得到七种配合物。以[Fe(CN)6]3-为前驱体得到配合物1,以[Mo(CN)8]4-作为构筑单元得到配合物2和3,以[Fe(CN)6]4-为配位前体与稀土离子(Ce3+, La3+, Nd3+, Gd3+)反应得到一系列配合物4、4a、4b和4c。第二部分,以水杨醛缩2-氨基-2-甲基-1,3-丙二醇Schiff碱(H3L)及4,4-联吡啶氮氧化物(bpdo)为配体,得到了两个锰的配合物5,6。九种配合物化学式为：(1)[CuⅡ(Hydeten)2]2[FeⅡ(CN)6]·2H2O(2)[CeⅢ2(ida)2(H2O)8][MoⅣ(CN)8]·H2O(3)[LaⅢ2(ida)2(H2O)8][MoⅣ(CN)8]·H2O(4) NaLnⅢ[FeⅡ(CN)6]·3H2O (Ln=Ce, La, Nd, Gd)(5) [MnⅣ(HL)2]·CH3CN(6) [MnⅡ(bpdo)6](ClO4)2对合成的配合物进行了红外光谱和ICP表征,并用X-ray单晶衍射法测定了配合物1,2,4,5和6的结构,结构测定表明配合物1由构筑单元[Fe(CN)6]4-和[Cu(Hydeten)2]2+组成,该配合物属于P21空间群,为手性分子；由配体亚氨基二乙酸(IDA)和稀土离子形成的配合物2为二维层状结构,抗衡离子模板[Mo(CN)8]4-嵌在二维层内；配合物4为三维网状结构,Na+填充在三维结构的空穴内；配合物5由单核锰构成,通过分子间氢键作用形成一维超分子链；配合物6是由Mn(Ⅱ)和4,4-联吡啶氮氧化物(bpdo)形成的单核配合物,ClO4-作为配阴离子平衡电荷。根据R光谱及ICP表征,推测配合物3与配合物2结构类似,为二维层状。更多还原

【Abstract】 The thesis includes two parts. In part 1, the assembly of three building blocks, K3[Fe(CN)6], K4[Mo(CN)8] and K4[Fe(CN)6] with transition metal and lanthanide ions, respectively, leads to the formation of seven compounds. Compound 1 is based on [Fe(CN)6]3-, compound 2 and compound 3 consists of [Mo(CN)8]4- and lanthanide ions (Ln=Ce, La). The reactions between [Fe(CN)6]4- and Ln(Ⅲ) ions, where Ln=Ce(4), La(4a), Nd(4b), Gd(4c), form a series of compounds. In part 2, compound 5 and compound 6 were obtained by the reaction of bivalent manganese ions with Schiff base (H3L) and 4,4’-bipyridine-N,N’-dioxide (bpdo).The formulae of nine compounds are as follows:(1)[CuⅡ(Hydeten)2]2[FeⅡ(CN)6]·2H2O(2)[CeⅢ2(ida)2(H2O)8][MoⅣ(CN)8]·H2O(3)[LaⅢ2(ida)2(H2O)8][MoⅣ(CN)8]·H2O(4)NaLnⅢ[FeⅡ(CN)6]·3H2O (Ln= Ce, La, Nd, Gd)(5)[MnⅣ(HL)2]·CH3CN (6)[MnⅡ(bpdo)6](ClO4)2All the compounds were characterized by IR and ICP, and the structures of 1, 2,4,5 and 6 were determined by X-ray single crystal diffractometry. The results indicate that the structure of compound 1 consists of trinuclear molecules formed by [Fe(CN)6]4- and [Cu(Hydeten)2]2+ building blocks, which crystallizes in the chiral space group P21. Compound 2 exhibits a two-dimensional layer-like structure extended by IDA ligands and lanthanide ions, while the counter anion, [Mo(CN)8]4- as template, is situated within the two-dimensional layers. The structure of compound 4 shows a 3D network. Na+ is located in the cavity of the network. Compound 5 consists of mononuclear manganese(Ⅳ) structure, which is linked by intermolecular hydrogen bonds to form supramolecular one-dimensional chain-like structure. Compound 6 is comprised of Mn(Ⅱ) and bpdo ligands, which is a mononuclear molecule. The two ClO4- ions act as counter anions to balance charge. The results of IR spectrum and ICP analysis suggest that compound 3 has a two-dimensional layer-like structure similar to compound 2.更多还原
