Abstract
Mossbauer effect and electrical measurements in the temperature range 295-3 80 K for hexane-diammonium tetrachloro-ferrate are presented. The electric permittivity and conductivity reveal the presence of two phase changes at 3 25 and 345 K. The former is related to a rotational transition. Mossbauer p arameters reflect only the 345 K transition, which is ascribed to a transit ion of a displacive type. (C) 2000 Published by Elsevier Science Ltd.
