Abstract

Dimethyltetrathiafulvalene-p-chloranil (DMTTF-CA), showing a particular neutral(N)-ionic(I) transition from a N phase into a NI coexisting phase by cooling, was structural analyzed by X-ray at 29K, 48K, 109K and 293K. Below Tc of 65K, changes observed in unit cell parameters, bond lengths and anisotropic temperature factors indicate 1) a increase in degree of charge transfer(CT) from a DMTTF donor to a CA acceptor and 2) a formation of a molecular dimerization, in I part of the coexisting phase. A possible staging superlattice was not observed.
