Aqua(benzene-1,3-dicarboxylato)zinc(II).
The title compound, poly[[aquazinc(II)]-mu-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=O...H-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) degrees ] and the alignment of the water molecules. Bridging isophthalate groups align to form approximate centrosymmetric motifs.
