Abstract
The crystal structure of the title compound, [(NH3)5Ru·N(CH)4N·Ru(NH3)5] Br10/3Cl5/3·4H2O, has been determined from X-ray diffractometer data by direct methods and refined by full-matrix least squares to R 0.062 for 2 951 observed reflections. Crystals are orthorhombic, probable space group Pnnm, a= 17.790(4), b= 11.590(2), c= 7.096(1)Å, Z= 2. The cation has exact crystallographic symmetry of at least 2, and approximate mmm symmetry; Ru–N(pyrazine) is 2.006(6), Ru–NH3(trans) 2.127(7), and Ru–NH3(cis) 2.098(5) and 2.122(5)Å. The anions, together with the water molecules, are highly disordered.Keywords
