✦ Synopsis
In the title complex, [Zn(C~6~H~5~N~2~O~2~)~2~(H~2~O)~2~], the Zn^2+^ cation lies on an inversion centre and the coordination geometry is distorted octahedral, with two N atoms and two O atoms from the 5-methylpyrazine-2-carboxylate ligand in the equatorial plane. The two remaining coordination sites are occupied by two water molecules. The crystal structure is stabilized by a network of O—H...O hydrogen-bonding interactions, forming a two-dimensional supramolecular structure.
