catena-Poly[[pyridinecopper(II)]-μ-N-[(2-oxido-1-naphth-yl)methyl-ene]glycinato].

In the title compound, [Cu(C(13)H(9)NO(3))(C(5)H(5)N)], 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)†à ] is much longer than the basal Cu-O and Cu-N bonds [1.9139†(14)-2.0136†(17)†à ]. The carboxyl-ate group bridges Cu(II) atoms, forming a zigzag chain along the a axis.
