Abstract
Systematic investigations of the formation conditions of the different polynuclear bismuth cations succeeded in obtaining single crystals of different phases. Bi 5(AlCl 4) 3 was obtained by a modification of the methods given by Corbett as black plate-like crystals. The single-crystal structure determination shows the compound to be rhombohedral, space group R3̄ c, with a hex = 11.860 A ̊ , c hex = 30.100 A ̊ . The Bi 5 3+ polycation forms the predicted structure of a trigonal bipyramid with Bi-Bi bond distances of 3.318 Å in the equatorial plane and 3.007 Å for the bond to the apices. The first is remarkably long compared with the values in Bi 9 5+ and Bi 8 2+. The structural relationships are discussed.
