Popis:	The crystal structures of the compounds trans-[Rh(en)2Cl2]Cl2 · H5O2 (I), trans-[Rh(en)2Cl2]ClO4 (II), and trans-[Rh(en)2Cl2]ReO4 (III) are determined. The crystal data are: I, a = 10.860(3) A, b = 7.795(2) A, c = 9.023(3) A; β = 111.56(10)°, P21/c space group, Z = 4, d x = 1.875 g/cm3; II, a = 6.593(2) A, b = 8.309(3) A, c = 11.922(4) A, α = 83.55(10)°, β = 79.80(10)°, γ = 75.38(10)°, P $$ \bar 1 $$ space group, Z = 2, d x = 2.106 g/cm3; III, a = 6.533(2) A, b = 16.391(4) A, c = 12.411(3) A; β = 98.30(10)°, P21/c space group, Z = 4, d x = 2.749 g/cm3. The compounds are examined by IR spectroscopy and powder XRD. The solubility of the isolated crystalline phases in water decreases in the following order: trans-[Rh(en)2Cl2]Cl2·H5O2 > trans-[Rh(en)2Cl2]ClO4 > trans-[Rh(en)2Cl2]ReO4.
