Abstract
The products of the extraction treatment of Rh(III) and Pd(II) nitrate-nitrite solutions are studied. The [Rh(Thio)6](NO3)3·3H2O and [Pd(Thio)4](NO3)2 complex salts are extracted and an X-ray diffraction analysis of single crystals is performed (BRUKER X8 APEX automated diffractometer, MoKα radiation, graphite monochromator, two-dimensional CCD-detector). [Rh(Thio)6](NO3)3·3H2O crystallographic characteristics are as follows: a = 15.1857(3) Å, b = 10.7292(2) Å, c = 18.8524(4) Å, β = 105.165(1)°, P21/c space group, Z = 4; [Pd(Thio)4](NO3)2: a = 5.8013(4) Å, b = 7.0981(5) Å, c = 11.4991(8) Å, α = 99.963(2)°, β = 101.410(2)°, γ = 102.229(2)°, P -1 space group, Z = 1.
