Abstract

Reactions of N‚N’-bis(3-methylpyridyl)oxalamide (L¹), N‚N’-bis(3-methylpyridyl)adipoamide (L²) or N‚N’-bis(3-methylpyridyl)sebaamide (L³) with 1,2,4,5-benzenetetracarboxylic acid (1,2,4,5-H₄BETC) and metal salt yield four coordination polymers: {[Cu₂(L¹)₂(1,2,4,5-BTEC)(H₂O)]·5H₂O}_n, 1, [Cu₂(L²)(1,2,4,5-BTEC)(H₂O)₄]_n, 2, [Cu₂(L³)(1,2,4,5-BTEC)(H₂O)₄]_n, 3, and [Ni(L²)(1,2,4,5-BTEC)_0.5(H₂O)₂]_n, 4. These polymers have been structurally characterized using single crystal X-ray crystallography. Complex 1 forms a 3D framework adopting a new (4.6²)₂(4².6².8²)(4².6⁴.8⁴)₂(6³.8³) topology, whereas the others display 2D layers with the bex topology for 2 and 3, and a rare 4,4L88 topology for 4. The structural diversity of these coordination polymers is influenced by the combined effects of metal identity and ligand flexibility, supported by the 1,2,4,5-BTEC^4- ligand. Their thermal properties have also been investigated.

苯四甲酸和双吡啶双酰胺配位聚合物的结构多样性

N'N'-双(3-甲基吡啶基)草酰胺（L1）、N'N'-双(3-甲基吡啶基)己二胺（L2）或 N'N'-双(3-甲基吡啶基)癸酰胺（L3）与 1,2,4,5-苯四甲酸（1,2,4,5-H4BETC）和金属盐反应生成四种配位聚合物：{[Cu2(L1)2(1,2,4,5-BTEC)(H2O)]-5H2O}n，1，[Cu2(L2)(1,2,4,5-BTEC)(H2O)4]n，2，[Cu2(L3)(1,2,4,5-BTEC)(H2O)4]n，3 和 [Ni(L2)(1,2,4,5-BTEC)0.这些聚合物的结构特征已通过单晶 X 射线晶体学研究得出。配合物 1 形成了三维框架，采用了新的 (4.62)2(42.62.82)(42.64.84)2(63.83) 拓扑结构，而其他配合物则显示出二维层，其中 2 和 3 采用了 bex 拓扑结构，而 4 则采用了罕见的 4,4L88 拓扑结构。在 1,2,4,5-BTEC4- 配体的支持下，这些配位聚合物的结构多样性受到了金属特性和配体灵活性的共同影响。我们还研究了它们的热特性。

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
