Tetrakis(triethylammonium) Hexakis(isothiocyanato-N)nickel(II)

The unit cell of the title compound, (C₆H₁₆N)₄[Ni(NCS)₆], contains two independent centrosymmetric [Ni(NCS)₆]^4- anions and eight Et₃NH⁺ cations. The Ni-N distances are in the range 2.072 (4) to 2.097 (4) Å. In one anion, all six S atoms are hydrogen bonded to cations, but the second anion is involved in only two hydrogen bonds. There are no significant geometrical differences between the two anions.
