Popis:	C 1 3 H I 3 N 2 0 + . B r is orthorhombic, Pcab, Z = 8, a = 11.649 (5), b = 12.218 (7), c = 17.775 (10)]k; d c = 1.539 Mg m -a, lt(Mo Ka) = 3.431 mm -~. R w = 0.041 for 1634 reflections. CI3HI3N20+.CHaSO3 is monoclinic, P2~/b, Z = 4, a = 7.044(1), b = 13.113(7), c = 16.50(1),~, 7 = 93"10(2)°; d c = 1.416 Mg m -a, ~t(Mo Ka) = 0.234 mm-L Rw = 0.042 for 1960 reflections. The structure of the bromide was solved via heavy-atom techniques. The MULTAN solution of the methylsulphonate gave a translationally misplaced cation. The problem was solved using the Karle refinement option. Both molecules have their oxime moieties in the (E) configuration.
