CRYSTAL STRUCTURE OF [Rh(H<sub>2</sub>O)<sub>5</sub>Cl](C<sub>7</sub>H<sub>7</sub>O<sub>3</sub>S)<sub>2</sub> AND Cs[Rh(H<sub>2</sub>O)<sub>5</sub>NO<sub>3</sub>](C<sub>7</sub>H<sub>7</sub>O<sub>3</sub>S)<sub>3</sub>xH<sub>2</sub>O
The crystal structures of the compounds with the composition [Rh(H2O)5Cl](C7H7O3S)2 (I) and Cs[Rh(H2O)5NO3](C7H7O3S)3×H2O (II) are determined. Crystallographic data for I: a = 10.063(10) Å, b = 7.771(8) Å, c = 13.524(15) Å; b = 100.44(3)°, space group P 21, Z = 2, d calc = 1.823 g/cm3; for II: a = 16.221(3) Å, b = 9.646(19) Å, c = 21.307(4) Å, b = 92.06(3)°, space group P 21, Z = 8, d calc = 1.833 g/cm3. The compounds are characterized by IR spectroscopy and powder X-ray diffraction. The rhodium atoms have a distorted octahedral environment consisting of five oxygen atoms of coordinated water molecules and one chloride ion (I)/oxygen atom of the nitrate ion (II) with the following distances: Rh-OH2O of 1.993-2.075 Å and Rh-Cl of 2.270 Å for I; Rh-OH2O of 1.996-2.031 Å and Rh-ONO3 of 1.990 Å for II.
