Abstract: The title compound, [Pb₂(C₂H₃O₂)₄(C₈H₁₀O₂)]_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^IIO₆ core with the empty space around the metal ion filled by the stereochemically active 6s² 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-HO hydrogen bonds.
