Abstract

Acyclic tetraazametal gold(III) perrhenate complex [Au(C9H19N4)](ReO4)2 is synthesized. The 3D crystal structure of the complex is stabilized by weak secondary interactions (N-H…O, C-H…O, С-H…Au hydrogen bonds, and Au…O contacts). The translation sublattice method shows that the motif of the mutual arrangement of cations can be considered to be pseudohexagonal. The product of the thermal decomposition of [Au(C9H19N4)](ReO4)2 in a hydrogen atmosphere is a mixture of nanocrystalline phases (HCP phases based on Re and Au) with the coherent scattering region of 24 nm and 34 nm, respectively.
