Abstract

Abstract Inelastic incoherent neutron scattering (IINS) spectra and neutron powder diffraction (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 both compounds the phase transition occurring at TC3 is connected with a change of the crystal structure, and that occurring at TC2 with a change in the rate of the reorientational motions of H2O ligands.
