Abstract

The physical properties of the new complex and mixed salt (TMA+)3(I 3 ) (TCNQ)2(TCNQo) characterized recently are presented. Crystallographic study at room temperature has shown a diffuse scattering which indicates the existence of a 1-D superlattice. From dynamic (EPR) and static magnetism investigations and the existence of a specific heat anomaly an electronic PEIERLS distorsion is postulated. However the semi conductive behaviour of this salt is evidenced by the d.c. conductivity and the thermoelectric power results. A comparison with similar situations in TTF-TCNQ and mainly in KCP is presented.
