The low and high temperature phase transitions in the family of compounds (DT-TTF){ 4 }[ M(L){ 2 ] 3 }, M = Au, Cu and L = pds, pdt

The compounds of the family (DT-TTF) 4 [M(L) 2 ] 3 where M=Au, Cu and for L=pds, pdt have related structures and present a series of 1 st and 2 nd order phase transitions within a semiconducting regime which were studied by electrical transport and X-ray diffraction experiments.
