title: catena-Poly[[[μ-aqua-penta-aqua-dizinc(II)]-μ(4)-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].
abstract: The asymmetric unit of the title compound, {[Zn(2)(C(10)H(2)O(8))(H(2)O)(6)]·2H(2)O}(n), contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxyl-ate groups belonging to distinct halves of benzene-1,2,4,5-tetra-carboxyl-ate (tbec) tetra-anionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octa-hedral knots. O-H⋯O hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.
