For the first time the data on resistance anisotropy in the (ET) 2TlHg(SCN) 4 salt family are presented. The data are discussed taking into account the Fermi surface of the compounds. The pressure effect on the low-temperature phase transition in (ET) 2TlHg(SCN) 4 is investigated. It is found that pressures of about 3 kbar suppress the transition. The T- P phase diagram is plotted.
