Crystal structure of [Rh(H2O)5Cl](C7H7O3S)2 and Cs[Rh(H2O)5NO3](C7H7O3S)3•H2O

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; β = 100.44(3)°, space group P21, Z = 2, dcalc = 1.823 g/cm3; for II: a = 16.221(3) Å, b = 9.646(19) Å, c = 21.307(4) Å, β = 92.06(3)°, space group P21, Z = 8, dcalc = 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–\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${O_{{H_2}O}}$$\end{document} of 1.996-2.031 Å and Rh–\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${O_{N{O_3}}}$$\end{document} of 1.990 Å for II.
