In the crystal structure of the title adduct, C8H12N2O2·[Zn(NCS)2(H2O)2], the organic and inorganic molecules are connected by O—H
O 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.

The title mononuclear complex, [Zn(I)2(C6H7NO)2], lies on a special position of site symmetry 2. The Zn atom is coordinated by two I and two O atoms in a tetrahedral geometry. There is a π–π stacking interaction of the 4-methylpyridine N-oxide units.
