In the title compound, [Cu(C₁₃H₉NO₃)(C₅H₅N)], the Cu^II atom is coordinated in a distorted square-pyramidal geometry, with two N and two O atoms in the basal positions and one O atom in the apical position. The apical Cu-O bond [2.3520 (16) Å] is much longer than the basal Cu-O and Cu-N bonds [1.9139 (14)-2.0136 (17) Å]. The carboxylate group bridges Cu^II atoms, forming a zigzag chain along the a axis.
