项目摘要

Design and synthesis of molecular based materials is a booming field of research in crystal engineering. Hydrogen bonding interaction is one of the active tools to construct metal organic suprastructures. In this context, usage of mixed organic ligands helps to get predictable molecular architecture having potential properties such as magnetism, conductivity and non-linear optics.Chloranilic acid is one the member of oxocarbon family provides 1D chains and 2D layers with various metal ions. We have synthesized iron assembled compound of chloranilic acid, {[Fe(CP*)ィイD22ィエD2][Fe(CA)ィイD22ィエD2(HィイD22ィエD2O)ィイD22ィエD2]}<D2n>D2 (1) (HィイD22ィエD2CA = chloranilic acid, Cp*ィイD1-ィエD1 = decamethyl cyclopentadienide) and Cu and Zn assembled compounds of chloranilic acid and tptz, {[M(CA)(tptz)(HィイD22ィエD2O)](HィイD22ィエD2O)} (tptz = 2,4,6-tris(2-pyridyl)-l,3,5,-triazine, M = CuィイD12+ィエD1 (2), ZnィイD12+ィエD1 (3). Here the crystal structures of the three compounds are described.Compound 1 consists of 2D anionic layer {[Fe(CA)ィイD22ィエD2(HィイD22ィエD2O)ィイD22ィエD2]ィイD1-ィエD1}n and [Fe(CP*)ィイD22ィエD2]ィイD1+ィエD1 guest cations. The geometry around the iron(III) ion in the layer is a distorted octahedron, where four oxygen atoms from two CAィイD12-ィエD1 and two oxygen atoms from two water molecules are coordinated (Fig. 1). The octahedral units make 2D layer by hydrogen bonding interaction, which occurs between the terminal oxygen atoms of CAィイD12-ィエD1 and the coordinated water molecules. The [Fe(CP*)ィイD22ィエD2]ィイD1+ィエD1 cations are intercalated between the layers by electrostatic interaction.Compound 2 and 3 are isomorphous and are made of CAィイD12-ィエD1 and tptz coordinated octahedral building units, which make 1D chains by hydrogen bonding interaction. Each metal ion is coordinated by two oxygen atoms from one CAィイD12-ィエD1, three nitrogen atoms from one tptz and one oxygen from a water molecule. Interstitial water molecules are included by hydrogen bonding interaction.

基于分子材料的设计和合成是晶体工程研究的蓬勃发展领域。氢键相互作用是构建金属有机超构造的活跃工具之一。在这种情况下，混合有机配体的使用有助于获得具有潜在特性的可预测分子结构，例如磁性，电导率和非线性光学。氯氨酸是氧碳家族的成员之一，可提供一维链和2D层，并具有各种金属离子。 We have synthesized iron assembled compound of chloranilic acid, {[Fe(CP*) D22E D2][Fe(CA) D22E D2(Hi D22E D2O) D22E D2]}<D2n>D2 (1) (Hi D22E D2CA = chloranilic acid, Cp*i D1-E D1 = decamethyl cyclopentadienide) and Cu and Zn assembled compounds of chloranilic acid and tptz, {[M(CA)(tptz)(Hii D22E D2O)](Hii D22E D2O)} (tptz = 2,4,6-tris(2-pyridyl)-l,3,5,-triazine, M = Cuii D12+E D1 (2), ZnI D12+E D1（3）描述了三种化合物的晶体结构。层是扭曲的八面体，其中两个水分子的四个氧原子是协调的（图1）。在静电相互作用的层之间。cound2和3是同构的，由CAII D12IE D1和TPTZ协调的八面体建筑单元制成，通过氢键相互作用使1D链形成。每个金属离子由一个来自一个CAII D12IE D1的两个氧原子协调，一个来自一个TPTZ的氮原子和一个来自水分子的氧气。氢键相互作用包括间质水分子。
