Abstract

Three coordination polymers {[Co(bte)(NO₂-1,3-bdc)(H₂O)]⋅H₂O}_n (1), {[Co(btp)(NO₂-1,3-bdc)(H₂O)]⋅2H₂O}_n (2) and {[Co₂(btb)₂(NO₂-1,3-bdc)₂]⋅2H₂O}_n (3) were synthesized by the different spacer lengths and conformational flexibilities bte, btp, btb and the rigid NO₂-1,3-bdc. 1 forms an independent 1D MONT and a (1D → 2D) interdigitated array. In 2, two identical undulated (4,4) networks are parallel stacking to give a double-layer. In 3, the btb ligands connect the [Co₂(NO₂-1,3-bdc)₂]_n ladders to construct an unusual 3D network with point symbol 4⁶⋅6⁷⋅8² based on [Co₂(COO)₂] unit. The thermal stability and the UV–vis spectra of 1, 2 and 3 were investigated.

基于柔性双(三唑)和5-硝基间苯二甲酸酯的三种钴配位聚合物的合成、结构和性能

利用不同的间距长度和构象柔性(bte、btp、btb)以及刚性NO2-1、3-bdc和NO2-1、3-bdc (H2O))，合成了3种配位聚合物{[Co(btp)(NO2-1,3-bdc)(H2O)]·2H2O}n(1)、{[Co(btp)(NO2-1,3-bdc)(H2O)]·2H2O}n(3)。1形成一个独立的1D MONT和一个(1D→2D)互指阵。在图2中，两个相同的波动(4,4)网络被并行堆叠以得到一个双层。在3中，btb配体连接[Co2(NO2-1,3-bdc)2]n阶梯，构建了基于[Co2(COO)2]单元的点符号为46⋅67⋅82的不寻常的三维网络。考察了1、2、3的热稳定性和紫外可见光谱。

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
