Abstract
The prolonged reactions of 3-chloroaniline with CuBr2 in HBr solution yielded three crystalline compounds involving brominated anilinium cations. The first, (C6H3BrClNH3)Br, is the bromide ion salt of the 6-bromo-3-chloroanilinium cation. The compound is monoclinic, space group P21/c, with a = 10.520(4), b = 8.4238(13), c = 10.502(4) A and β = 108.55(1)° with Z = 4. The compound with stoichiometry (C6H3BrClNH3)2CuBr3, contains the 4-bromo-3-chloroanilinium cation. It is triclinic, space group P-1, with a = 8.217(2), b = 14.496(4), c = 16.993(4) A, α = 77.46(2), β = 86.00(3), γ = 89.22(2)° with Z = 4. Finally, the third compound contains the dibrominated cation, 4,6-dibromo-3-chloroanilinium, with stoichiometry (C6H3Br2ClNH3)CuBr2. It is orthorhombic, space group Pnma, with a = 7.2177(2), b = 29.7188(3), and c = 10.9309(2) A with Z = 8. The latter two salts contain Cu(I) species, obtained by the reduction of the original Cu(II) ions during the bromination process. The first of these two Cu(I) salts contain...
