The title complex, [Zn(C(10)H(8)N(2))(2)(H(2)O)(4)](C(9)H(7)O(3))(2), was obtained by the hydro-thermal reaction of zinc sulfate with mixed 4-hydroxy-lcinnamic acid (H(2)L) and 4,4'-bipyridine (4,4'-bipy) ligands. The complex consists of a centrosymmetric [Zn(4,4'-bipy)(2)(H(2)O)(4)](2+) cation with the metal centre in a distorted ZnN(2)O(4) coordination, and of two HL(-) anions. Extensive O-H⋯O and O-H⋯N hydrogen-bonding inter-actions between the constituents lead to the formation of a three-dimensional network.
