Abstract

The family of charge transfer salts (DT-TTF)nM(mnt)2, with M=Au, Ni, Pt, Fe and Co, shows a wide range of interesting electrical and magnetic properties. Salts with M=Au, Ni and Pt, with n=2 are isostructural. The Au compound, is a semiconductor and presents a localised regime of charge carriers in DT-TTF chains, behaving as a spin-ladder system. The Ni and Pt analogues have a delocalised regime with higher conductivity at room temperature and a transition to an insulator state at 120 and 127 K respectively. The Fe and Co compounds form ionic salts with n=1 and present poorer semiconducting properties. For M=Fe, crystals of different morphologies and the observation of three different transport properties denote the existence of different phases.
