Abstract
The crystal structure of [Pt(En)2](ReO4)2 (En is ethylenediamine) is studied. The crystal chemical analysis is performed and the main factors affecting the packing of moieties in this structure are determined. Shown that thermal decomposition in the He atmosphere at 880 °C results in the formation of the Pt0.33Re0.67 solid solution with the hexagonal close packed lattice parameters а = 2.765 Å, c = 4.422 Å and the size of the coherent scattering regions of 42 nm.
