Abstract: In the crystal structure of the title adduct, C₈H₁₂N₂O₂·[Zn(NCS)₂(H₂O)₂], the organic and inorganic molecules are connected by O-HO hydrogen bonds, with OO distances ranging from 2.640  (2) to 2.677  (3)  Å. There are two independent 2,3,5,6-tetramethylpyrazine 1,4-dioxide molecules, both of which lie on crystallographic inversion centers; the asymmetric unit contains two organic half-molecules and one inorganic molecule.
