The refinements described here for (NEt4)[ZnI4] completely confirm the resu
lts previously obtained for the isostructural tetrabromocadmate at room tem
perature [Geselle & Fuess (1994). Acta Cryst. C50, 1582-1585]. Here again,
isolated MX4 (M = Zn and X = I) tetrahedra are accompanied by two cations i
n a 'swastika' conformation and a third in a virtually planar trans conform
ation. One of the former cations is particularly disordered.
