Abstract
Complex compounds cis-K[Rh(NH3)2Cl4]·KCl (I), cis-K[Rh(NH3)2Cl3(NO2)] (II), and K2[Rh(NH3)Cl5] (III) are synthesized. The single crystal X-ray diffraction analysis of the compounds obtained is performed at T = 296 K. Crystallographic data for I are: a = 11.822(5) Å, b = 11.608(5) Å, c = 8.196(4) Å, β = 107.56(2)°, space group C2/m, Z = 4, dcalc = 2.431 g/cm3. For II: a = 8.946(3) Å, b = 5.941(2) Å, c = 8.182(3) Å, space group Pmn21, Z = 2, dcalc= 2.509 g/cm3. For III: a = 13.464(6) Å, b = 9.989(4) Å, c = 6.932(3) Å, space group Pnma, Z = 4, dcalc = 2.675 g/cm3. The compounds are characterized by IR spectroscopy, powder X-ray diffraction, and chemical analysis. [ABSTRACT FROM AUTHOR]
