Abstract: The title compound, [Ni(C₂H₆OS)₆](NO₃)₂·2C₂H₆OS, comprises centrosymmetric [Ni(dmso)₆]²⁺ cations, nitrate anions and non-coordinated dimethyl sulfoxide solvent molecules. The octahedral geometry of the cation is very regular, with Ni-O interatomic distances and O-Ni-O interatomic angles falling within narrow ranges 2.0485  (9)-2.0665  (9)  Å and 89.12  (4)-93.27  (4)°, respectively. Two weak C-HO hydrogen-bonding contacts link cations and anions to form a chain which lies along the [111] direction.
