The unit cell of the title compound, (C6H16N)(4)[Ni-(NCS)(6)], contain
s two independent centrosymmetric [Ni(NCS)(6)](4-) anions and eight Et
(3)NH(+) cations. The Ni-N distances are in the range 2.072(4)-2.097 (
4) Angstrom. In one anion, all six S atoms are hydrogen bonded to cati
ons, but the second anion is involved in only two hydrogen bonds. Ther
e are no significant geometrical differences between the two anions.
