Arrangement of Rh3+ ions in fac-triamminetri­chlorido­rhodium from powder data and in fac-triammine­trinitratorhodium crystals twinned by merohedry

Abstract: The rhodium complexes [RhCl3(NH3)3], (I), and [Rh(NO3)3(NH3)3], (II), are built from octa­hedral RhX3(NH3)3 units; in (I) they are isolated units, while in (II) the units are stacked in columns with partially filled sites for the Rh atoms. The octa­hedra of monoclinic crystals of (I) are linked by N-H...Cl hydrogen bonds and the Rh3+ ions are located on the mirror planes. In the trigonal crystals of (II), the discontinuous `columns' along the threefold axis are linked by N-H...O hydrogen bonds. The structure of (I) has been solved using laboratory powder diffraction data, the structure of (II) has been solved by single-crystal methods using data from a merohedrally twinned sample. Both compounds possess low solubility in water.
