Crystal and molecular structure of [Au(C14H22N4)]ReO4
摘要:
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: D degrees = 7.733(2) , b = 11.368(2) , c = 11.685(2) , alpha = 116.23A degrees, beta = 104.26A degrees, gamma = 94.96A degrees; V = 870.3(3) (3), space group P(-1), Z = 2, d (calc) = 2.647 g/cm(3), 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-HaEuro broken vertical bar O, C-HaEuro broken vertical bar Au, C-HaEuro broken vertical bar pi and the AuaEuro broken vertical bar 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.

[Au(C14H22N4)][AuBr2] with two types of gold atoms (Au(III) and Au(I)) was obtained. In the cation 5,7,12,14-tetramethyl-1,4,8,11-tetraazacyclotetradeca-4,6,11,13-tetraenatogold(III), the Au atom is coordinated by four N atoms of the tetraazamacrocyclic amide ligand to make up a distorted square. The dibromoaurite(I) anion is linear. The conformation and packing of the structure is determined and stabilized by weak
