Two coordination polymers constructed by 5-[(4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylic acid and 2,2 ′ -bipyridine: syntheses, structures and luminescence properties

Coordination polymers (CPs) have attracted increasing interest in recent years. In this work, two new CPs, namely poly[[aquabis(2,2 ′ -bipyridine- κ 2N,N ′ ){ μ 3-5-[(4-carboxylatophenoxy)methyl]benzene-1,3-dicarboxylato- κ 4O1,O1 ′ :O3:O5}( μ -formato- κ 3O:O,O ′ )dicadmium(II)] monohydrate], {[Cd2(C16H9O7)(HCO2)(C10H8N2)2(H2O)] · H2O}n (1), and poly[[(2,2 ′ -bipyridine- κ 2N,N ′ ){ μ 3-5-[(4-carboxylphenoxy)methyl]benzene-1,3-dicarboxylato- κ 4O1,O1 ′ :O3:O5}manganese(II)] sesquihydrate], {[Mn(C16H10O7)(C10H8N2)] · 1.5H2O}n (2), have been prepared using the tricarboxylic acid 5-[(4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylic acid and 2,2 ′ -bipyridine under hydrothermal conditions. CP 1 displays a two-dimensional layer structure which is further extended into a three-dimensional (3D) supramolecular structure via intermolecular π – π interactions, while CP 2 shows a different 3D supramolecular structure extended from one-dimensional ladder chains by intermolecular π – π interactions. In addition, the solid-state luminescence spectra of 1 and 2 were studied at room temperature.
