The polymeric title compound, {[Cu(C8H3NO6)(C10H8N2)]·H2O}n, has two disordered nitro­terephthalate units located around centres of inversion; one functions in a μ2-bridging mode and the other in a μ4-bridging mode to surround the five-coordinated Cu atom in a square-pyramidal geometry. The crystal structure reveals a two-dimensional hydrogen-bonded network involving a water mol­ecule of crystallization.

In the title compound, [Pb(C7H4O5S)(C12H8N2)(H2O)]n, each PbII atom is coordinated by five O atoms from one water mol­ecule and three 3-sulfonatobenzoate ligands and two N atoms from one 1,10-phenanthroline. The 3-sulfonatobenzoate ligand serves as a μ3-bridge, linking three PbII atoms, and extends the structure into a one-dimensional ladder. The O—H...O hydrogen bonds generate a two-dimensional layer and enhance the stability of the structure.
