catena-Poly[[[triaquazinc(II)]-micro-2-nitroterephthalato-kappaO1:kappa2O4,O4'] monohydrate].
The title complex, {[Zn(C(8)H(3)NO(6))(H(2)O)(3)].H(2)O}(n), has a one-dimensional chain structure. The two carboxylate groups of the dianionic 2-nitroterephthalate ligand adopt mono- and bidentate chelating modes. The Zn atom shows distorted octahedral coordination, bonded to three O atoms from two carboxylate groups and three O atoms of three non-equivalent coordinated water molecules. The one-dimensional chains are aggregated into two-dimensional layers through inter-chain hydrogen bonding. The whole three-dimensional structure is further stabilized by inter-layer hydrogen bonds.
