摘要：

The structure of the title polyiodide compound, hexakis(dimethyl sulfoxide-O)nickel(II) tetraiodide, [Ni(C2H6OS)(6)]I-4, has been redetermined. The compound comprises discrete [Ni{(CH3)(2)SO}(6)](2+) cations and I-4(2-) anions. The polyhedron around the six-coordinate Ni atom is a distorted octahedron with the metal atom on a (3) over bar position and six equivalent Ni-O distances of 2.077 (2) Angstrom. The linear uncoordinated centrosymmetric I-4(2-) polyiodide ion represents a rare example of a tetraiodide ion. It exhibits a central I-I bond of 2.848(1) Angstrom and two terminal I-I bonds of 3.342 (2) Angstrom.
