The title compound, (H3O)[Ni(C2H6N4O2)3]I3 or (H3O)[Ni(H2oxado)3]I3, where H2oxado = oxamide dioxime, contains six [Ni(H2oxado)3]2+ cations, six H3O+ cations and eighteen I− anions in the unit cell. The Ni atom lies on a position of site symmetry 32 and the hydronium cation is disordered on a position of site symmetry \overline{3}. The crystal packing is consolidated by O—H⋯O hydrogen bonds that link the cations along c into positively charged pillars. The proton balancing the charge of the iodide ions is attached to the water molecule of crystallization, thus forming a hydronium ion.
