Sumario:The title compound, [Pb(2)(C(2)H(3)O(2))(4)(C(8)H(10)O(2))](n), has a polymeric structure, with acetatolead(II) chains and 2,5-dimethyl­benzene-1,4-diol mol­ecules forming bridges between two Pb(II) ions from neighbouring chains. Each Pb(II) centre is surrounded by eight O atoms; four belong to bidentate acetate ions, three to neighbouring bridging acetate groups and one to the 2,5-dimethyl­benzene-1,4-diol mol­ecule. The Pb(II) ions are chelated symmetrically and asymmetrically by acetate ligands. The coordination environment of the Pb(II) ion can be described as a hemidirected Pb(II)O(6) core with the empty space around the metal ion filled by the stereochemically active 6s (2) electron pair and two longer Pb—O contacts. The Pb—O distances are in the range of 2.355 (3)–2.994 (3) Å. Additionally, the crystal structure is stabilized by O—H⋯O hydrogen bonds.
