Abstract
The real part of the relative permittivity e; as well as the dielectric loss as
represented bye; for the compounds (CH2).(NH3)2MCI4_)Jrx (where
x = 0, 2, n = 2, 3 and M = CIl, Co) have been measured. The measurements
were carried out as a function of temperature and frequency. Both e;
and e; show the same relaxation phenomena which involves large reorientable
dipoles in the total polarization. The phase transition observed at
~ 312 K for e; and e; is expected from the variation in the spacing between
the adjacent metallic layers arising from the increase in the number of
carbon atoms and/or introducing the Br " ions in the out of plane position
