Abstract: The title compound, {[Cu(C₇H₄O₄)₂]·2CH₃OH}_n, forms a square-planar complex through two N,O-chelating pyridine-2,3-dicarboxylate ligands. Axial interactions between Cu^II and O atoms of the CO₂H groups in the meta-positions of adjacent ligands form one-dimensional chains. Incorporation of methanol into the structure results in O-HO hydrogen-bond interactions, which cross-link the chains into a three-dimensional network.
