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-BTEC4- ligand. Their thermal properties have also been investigated.
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.
