✦ Synopsis

The title compound, [Zn(C 5 H 3 N 2 O 2 ) 2 (H 2 O)] n , prepared by hydrothermal synthesis, is isostructural with its Fe II , Co II , Ni II and Cu II analogues. The asymmetric unit contains two bidentate pyrazine-2-carboxylate anions bonded to Zn II in the equatorial plane through one N and one O atom each. The Zn II atoms are linked into a chain by the second N atom of the anion bonding to an axial site of a neighbouring Zn II atom. The slightly distorted octahedral coordination around Zn II is completed by a water molecule, which forms hydrogen bonds to link the chains into a three-dimensional structure. The crystal studied was an inversion twin.
