摘要：
The crystal and molecular structure of [Au(C14H22N4)]Br has been determined. Monoclinic crystals, a = 12.592(2), b = 6.309(1), c = 19.628(2) Angstrom; beta = 98.00(1)degrees, V= 1544.1(4) Angstrom(3), Z = 4, d(calc) = 2.251 g/cm(3), space group C2/c. The structure consists of virtually planar centrosymmetric [Au(C14H22N4)](+) cations and BC anions. The coordination sphere of the gold atom involves four nitrogen atoms of the ligands, forming a planar square. The Au-N bond lengths are equal (the mean length is 1.982(7) Angstrom). The C-C and C-N bonds inside the beta-diiminate rings are delocalized. The parameters of the beta-diiminate rings of the [Au(C14H22N4)](+) cation are compared with the parameters of the related complexes.
