Abstract
Inelastic incoherent neutron scattering (IINS) spectra and neutron powder d iffraction (NPD) patterns, registered for [Co(H2O)(6)](ClO4)(2) at 18 - 270 K and for [Mn(H2O)(6)](BF4)(2) at 18 - 230 K, provided evidence that these crystals possess three solid phases in these ranges of temperatures. In bo th compounds the phase transition occurring at T-C3 is connected with a cha nge of the crystal structure, and that occurring at T-C2 with a change in t he rate of the reorientational motions of H2O ligands.
