Abstract

As an extension of our interest in pyridine-N-oxide-dicarboxylic acids, we report the design and synthesis of a 2D coordination polymer {[Cu(Hpydco)2]·2H2O}n (1) based on the pyridine-N-oxide-2,5-dicarboxylic acid ligand (H2pydco). 1 was characterized using elemental analyses, infrared spectroscopy, thermal gravimetric analysis, and single crystal X-ray diffraction. Structural analysis showed that this compound is a two-dimensional coordination polymer created by four-connected nodes defined by the copper ion and bridging Hpydco- ligands which created regular tetragons. In the packing, hydrogen bonds connect adjacent 2D sheets to extend the structure into a 3D architecture. Since H2pydco and pyridine-2,5-dicarboxylic acid have similar frameworks, we also highlight some areas of current interest in their coordination behavior by surveying reported structures (Cambridge Structural Database (CSD))and have investigated the influence of the N-oxide moiety on the coordination mode(s) in the crystal lattice.
