Substituent effects of two isophthalate derivatives on the construction of cadmium coordination polymers incorporating a dipyridyl ligand

In recent years, the design and construction of crystalline coordination complexes by the assembly of metal ions with multitopic ligands have attracted considerable attention because of the unique architectures and potential applications of these compounds. Two new coordination polymers, namely poly[[μ-trans-1-(2-aminopyridin-3-yl)-2-(pyridin-4-yl)ethene-κ²N:N'](μ₃-5-methylisophthalato-κ⁴O¹,O^1':O³:O^3')cadmium(II)], [Cd(C₉H₆O₄)(C₁₂H₁₁N₃)]_n or [Cd(5-Me-ip)(2-NH₂-3,4-bpe)]_n, (I), and poly[[μ-trans-1-(2-aminopyridin-3-yl)-2-(pyridin-4-yl)ethene-κ²N:N'](μ₂-5-hydroxyisophthalato-κ⁴O¹,O^1':O³:O⁵)cadmium(II)], [Cd(C₈H₄O₅)(C₁₂H₁₁N₃)]_n or [Cd(5-HO-ip)(2-NH₂-3,4-bpe)]_n, (II), have been prepared hydrothermally by the self-assembly of Cd(NO₃)₂·4H₂O and trans-1-(2-aminopyridin-3-yl)-2-(pyridin-4-yl)ethene (2-NH₂-3,4-bpe) with two similar dicarboxylic acids, i.e. 5-methylisophthalic acid (5-Me-H₂ip) and 5-hydroxyisophthalic acid (5-HO-H₂ip). The coordination network of (I) is a two-dimensional sql net parallel to (101). Adjacent sql nets are further linked to form a three-dimensional supramolecular framework via hydrogen-bonding interactions. Compound (II) is a two-dimensional (3,5)-connected coordination network parallel to (010) with the point symbol (6³)(5⁵6⁴7). As the other reactants and reaction conditions are the same, the structural differences between (I) and (II) are undoubtedly determined by the different substituent groups in the 5-position of isophthalic acid. Both (I) and (II) exhibit good thermal stabilities and photoluminescence properties.
