Poly­[lead(II)‐μ2‐aqua‐μ4‐tereph­thalato]

The title compound, Pb(C₈H₄O₄)(H₂O)]_n, forms as an insoluble product in the reaction of sodium terephthalate(2−) with Pb(NO₃)₂ in water. Analysis has shown that the crystal structure is centrosymmetric, with the asymmetric unit containing one formula unit. The lead geometry is hemidirected seven‐coordinate, with both monodentate and bidentate carboxyl­ate coordination modes present. The combination of hydrogen bonds and coordination bonds produces a three‐dimensional structure, including the first example, in a lead complex, of the common metal‐coordinated carboxyl­ate/water (6) graph‐set motif.
