Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The rhodium complexes [RhCl₃(NH₃)₃], (I), and [Rh(NO₃)₃(NH₃)₃], (II), are built from octahedral Rh<italic>X</italic>₃(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.</p> </abstract>
