Poly[μ-aqua-μ₄-naphthalene-1,8-dicarboxyl­ato-zinc(II)]

In the title complex, [Zn(C₁₂H₆O₄)(H₂O)]_n, a Zn^II polymer based on naphthalene-1,8-dicarboxyl­ate (1,8-nap), the Zn^II atoms adopt an elongated octa­hedral coordination geometry. A zigzag chain is formed by μ₂-aqua ligands and μ₂-carboxyl­ate groups of the 1,8-nap ligands. Adjacent parallel chains are further linked by 1,8-nap ligands, forming a twisted two-dimensional layer structure along the (100) plane.
