A new zinc polymer, {Zn(O2CC12H8CO2)(H2O)}n or {Zn(DPHA)(H2O)}n (O2CC12- H8CO2, DPHA = 1,1?-biphenyl-2,2?-dicarboxylate dianion) has been synthesized under hydrother- mal conditions. The crystal is of monoclinic, space group P21/c with a = 12.8418(5), b = 5.9505(2), c = 17.2989(5) ?, β = 104.020(2)o, V = 1282.52(8) ?3, C14H10O5Zn, Mr = 323.61, Z = 4, Dc = 1.676 g/cm3, μ = 1.930 mm-1, F(000) = 656, R = 0.0766 and wR = 0.1871 for 1775 observed reflections (I > 2σ(I)). It consists of Zn2(DPHA)2(H2O)2 units, which are further extended into a one-dimensional double helical-chain polymer via Zn–O bonding. The hydrogen bonding interactions extend the helical chains into a two-dimensional layer structure.
