Abstract
Perrhenate of the tetraazamacrocyclic complex of gold(III) [Au(C14H22N4)]ReO4 is synthesized. The crystal structure of the compound is determined by single crystal X-ray diffraction. The crystallographic data are as follows: а = 7.733(2) Å, b = 11.368(2) Å, c = 11.685(2) Å, α = 116.23°, β = 104.26°, γ = 94.96°; V = 870.3(3) Å3, space group P(-1), Z = 2, dcalc = 2.647 g/cm3, R = 0.0245. The packing of the complex is comprised of double stacks of cations and chains of anions linked into two-dimensional layers due to weak intermolecular interactions (non-classical hydrogen bonds C-H…O, C-H…Au, C-H…p and the Au…Au contacts). The thermal decomposition of the obtained compound in the hydrogen atmosphere is studied. According to the powder X-ray diffraction data, the product of the reduction of the synthesized salt is a mixture of nanocrystalline phases of Re and Au with the coherent-scattering regions of 17 nm and 13 nm respectively.
