Аннотация: 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 center dot center dot center dot 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 center dot center dot center dot 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.
