✦ Synopsis

The title compound, {[Cu(C 7 H 4 O 4 ) 2 ]Á2CH 3 OH} 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 CO 2 H groups in the meta-positions of adjacent ligands form one-dimensional chains. Incorporation of methanol into the structure results in O-HÁ Á ÁO hydrogenbond interactions, which cross-link the chains into a threedimensional network.

The 3-carboxyphenoxyacetate ligand in the title compound, [Cu(C 9 H 6 O 5 )(C 5 H 5 N) 3 ]Á3H 2 O, links adjacent tripyridinecopper(II) groups into a helical chain, which runs along the c axis of the hexagonal unit cell. The covalently bonded O atoms occupy trans sites in the basal plane of the squa
