Abstract

Two one-dimensional copper(II) coordination polymers constructed from 2-hydroxypyrimidine-4,6-dicarboxylic acid (H ₃hpdc), [Cu ₂(Hhpdc) ₂(NH ₃) ₂]·2NH ₃·H ₂O (1) and [Cu(NH ₃) ₄(H ₂O)][Cu ₂(hpdc) ₂(NH ₃) ₂]·2H ₂O (2), have been synthesized and characterized by X-ray single-crystal diffraction analysis and variable temperature magnetic susceptibility measurements, etc. Despite the different deprotonated forms of H ₃hpdc in 1 and 2, hydroxy-oxo tautomerism optimizes the coordination preferences of the ligands, presenting unique coordination polymers containing similar chain structures with different charge states. Moderate antiferromagnetic coupling interactions between adjacent Cu (II) ions are observed in two compounds.
