Poly[[bis-(μ-3-amino-5-carb-oxy-benzoato-κ(2)N:O(1))diaqua-zinc] dihydrate].
The Zn(II) atom in the title polymeric compound, {[Zn(C(8)H(6)NO(4))(2)(H(2)O)(2)]·2H(2)O}(n), lies on a center of inversion and is coordinated by two amine N atoms and two carboxyl-ate O atoms from two 3-amino-5-carb-oxy-benzoate anions along with two water mol-ecules in a distorted octa-hedral geometry. The bridging nature of the anion generates a layer motif parallel to (100). Hydrogen bonds of the N-H⋯O and O-H⋯O types exist in the structure. One H atom of the coordinated water mol-ecule and one H atom of the solvent water mol-ecule are each disordered over two positions in a 1:1 ratio.
