Aqua(benzene-1,3-dicarboxylato)zinc(II)

The title compound, poly­[[aqua­zinc(II)]‐μ‐benzene‐1,3‐di­carboxyl­ato‐O1:O1′:O2], [Zn(C8H4O4)(H2O)]n, forms a metal–organic coordination network that consists of tetrahedral Zn atoms bonded to one water mol­ecule and three carboxyl­ate groups. Isophthalate groups bridge the four‐coordinate Zn centers to generate two‐dimensional architectures in the ac plane. These planar zinc isophthalate motifs are linked by infinite C=O⃛H—O—H interactions along the a axis to form a chiral framework. The observed polar structural pattern originates due to the distorted tetrahedral Zn centers [O—Zn—O 100.7 (2)–136.0 (1)°] and the alignment of the water mol­ecules. Bridging isophthalate groups align to form approximate centrosymmetric motifs.
