At pressured above 5-7 kbar (depending on the temperature), the complex (TSeT)2Cl undergoes a first-order phase transition into a new metallic state that is stable in the entire investigated temperature range. The resistivity of the high-pressure phase decreases with decreasing temperature and assumes a residual value of the order of 10 ~5 Ω-cm below 10-15 K.
