Abstract

The crystal structure of a double complex salt of the composition [Au(en) 2] 2[Cu(C 2O 4) 2] 3·8H 2O (en = ethylenediamine) at 150 K is determined by single crystal X-ray diffraction. The crystal data for C 20H 48Au 2Cu 3N 8O32 are: a = 9.1761(3) Å, b = 16.9749(6) Å, c = 13.4475(5) Å, β = 104.333(1)°, V = 2029.43(12) Å 3, P2 1/c space group, Z = 2, d x = 2.450 g/cm 3. It is demonstrated that the thermal decomposition of the double complex salt in a helium or hydrogen atmosphere affords the solid solution Au 0.4Cu 0.6. Original Russian Text
