title: Bis(4,4'-bipyridine-kappaN)bis(hydrogen phthalato)-kappa2O,O';kappaO-zinc(II).
abstract: The title compound, [Zn(C8H5O4)2(C10H8N2)2], was obtained by the hydrothermal reaction of ZnSO4.7H2O with phthalic acid (H2pht) and 4,4'-bipyridine (4,4'-bipy). Crystallographic analysis shows that it has a one-dimensional double-chain structure via hydrogen-bonding interactions. Each Zn(II) atom, adopting a distorted tetrahedral geometry, is coordinated by two N atoms from two 4,4'-bipy ligands, with Zn-N distances of 2.054 (4) and 2.104 (4) A, and by two O atoms from symmetry-related Hpht- ligands, with Zn-O distances of 1.921 (4) and 2.019 (4) A.
