✦ Synopsis

Crystals of the title compound, [Co(C~8~H~4~O~5~)(H~2~O)~3~]~n~, were obtained by hydrothermal methods. Each Co^II^ ion is six-coordinated by two O atoms from one 5-hydroxybenzene-1,3-dicarboxylate (L) ligand, one O atom from another L ligand and three water molecules [Co—O = 2.016 (3)–2.324 (3) Å]. Each ligand L, acting in a tridentate mode, bridges two Co ions, resulting in the formation of polymeric zigzag chains extending along the [110] direction. The crystal packing is stabilized by an extensive network of O—H...O hydrogen bonds.

The title compound, {(C 10 H 10 N 2 )[Cu 2 (C 5 HN 2 O 4 ) 2 ]} n , has been synthesized under hydrothermal conditions. The self-assembly of the pyrazole-3,5-dicarboxylate ligands and Cu II atoms results in a one-dimensional anionic chain, in which the Cu II atom is five-coordinate in a square-pyram
