Abstract

The crystal structure of [NBu n4 ]f AlI4] has been determined from counter data, and refined by full-matrix least-squares techniques. The crystals belong to the monoclinic space groupP21/n (an alternate setting ofP21/c-C 52h , No. 14) witha=11.661(3),b=20.828(5),c=11.674(3) Å,β=98.39(2)°, andD calc=1.84 g cm−3 forZ=4. The finalR value for 1587 observed reflections is 0.051. The structure consists of discreet [NBu n4 ]+and [AlI4] ions. The [AlI4] anion is approximately tetrahedral and exhibits an average Al-I bond length of 2.52(1) Å. The closest cation-anion, I⋯C, contact is ¯4 Å. The compound was isolated from the reaction of I2 with [NBu n4 ][Al2Me6I].
