Spectroscopic, thermal and structural studies of new -leucine and -leucine complexes with chloranilic acid
Autor: Zbigniew Rozwadowski, Joanna Hetmańczyk, Jan K. Maurin, Andrzej Pawlukojć, J. Nowicka-Scheibe, Wojciech Schilf
Publikováno v: Journal of Molecular Structure. 1133:464-471
New molecular complexes of l -leucine and d -leucine with chloranilic acid have been synthesized. Crystal structures of these crystals have been solved; they crystallize in non-centrosymmetric monoclinic P21 space group. In the crystal, leucine molec

Dynamics of NH3 ligands and ClO4− anions in the phase transition in [Cd(NH3)6](ClO4)2 studied by x-ray powder diffraction, neutron scattering methods and infrared spectroscopy
Autor: Joanna Hetmańczyk, Łukasz Hetmańczyk
Publikováno v: Journal of Physics and Chemistry of Solids. 101:34-44
Phase transition, reorientational dynamics of NH 3 ligands and ClO 4 − anions and crystal structure changes were investigated using x-ray powder diffraction (XRPD), neutron powder diffraction (NPD), quasi-elastic neutron scattering (QENS) and Fouri

Phase transition, structure and reorientational dynamics of $H_2O$ ligands and ${ReO_{4}}^{-}$ anions in $[Ba(H_2O)_3](ReO_4)_2 \cdot H_2O$
Autor: Łukasz Hetmańczyk, Katarzyna Gąssowska, Joanna Hetmańczyk
One, low-temperature phase transition (PT) was detected for [Ba(H2O)3](ReO4)2⋅H2O, in the temperature range of 135–295 K by means of differential scanning calorimetry (DSC). The mean value of the PT temperature is T C h = 275.0 K (onset on heatin
