Abstract
A ferroelectric ortho-palladated dimer derived from chiral imines with two chiral terminal chains in the aromatic ring has been characterize d by dielectric permittivity, polarization, X ray and heat capacity me asurements. An anomalous behaviour has been detected in the low temper ature range of the SmC phase. A new molecular arrangement has been fo und on cooling prior to the crystallization not detected before by DSC experiments.
