Crystal-structure aspects of solid-state inner-sphere isomerization in nitro(nitrito)pentaamminecobalt(III) complexes

The results of spectral and X-ray diffraction studies into solid-state inner-sphere linkage isomerization of cobalt(III) pentaammine complexes are generalized (including studies under high hydrostatic pressures). The main goal was to establish how this isomerization is affected by the complex cation surrounding (modified by a change in the outer-sphere anion, polymorphic modification, or by application of hydrostatic pressure to the sample) and to determine the response of the crystal surrounding to the inner-sphere isomerization in the complex cations.
