Poly[trans-diaquabis-[μ(2)-2-(pyridin-3-yl)acetato-κN:O]-zinc].

In the title coordination polymer, [Zn(C(7)H(6)NO(2))(2)(H(2)O)(2)](n), the Zn(II) cation is located on an inversion center and is coordinated by four pyridyl-acetate anions and two water mol-ecules in a distorted ZnN(2)O(4) octa-hedral geometry. The pyridine-N and carboxyl-ate-O atoms of the pyridyl-acetate anion connect to two Zn(II) cations, forming a two-dimensional polymeric complex extending parallel to (212). Inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonding is present in the crystal structure.
