Abstract
The crystal structures of compounds of the composition [Rh(H2O)6]2(SO4)3·5H2O (I) and [Rh(H2O)6]PO4 (II) are determined. Crystallographic data for I: a = 7.272(9) Å, b = 27.047(1) Å, c = 12.464(9) Å, β = 97.038(10)°, P21 space group, Z = 4, dx = 2.184 g/cm3; for II: a = 9.746(6) Å, b = 6.877(7) Å, c = 23.623(6) Å, β = 100.601(10)°, C2/c space group, Z = 8, dx = 2.611 g/cm3. Compounds are analyzed by IR spectroscopy and powder XRD. Crystalline phase I is well soluble in water, whereas II is almost insoluble.
