摘要：

The structure and the temperature dependence of the resistivity, thermopower and ac-susceptibility of the new organic metal (BEDO - TTF)2ReO4(H2O) was investigated. The resistivity and thermopower data indicate phase transitions at 213 K, around 90 K and 35K. Below 2.5 K an onset to superconductivity is observed in the resistivity data. Superconductivity was suppressed in the resistivity at 1.3 K by applying a magnetic field of about 0.2 T. Ac-susceptibility data indicate that superconductivity is a bulk effect in (BEDO - TTF)2ReO4(H2O) but the onset for superconductivity observed in the ac - susceptibility is only at 0.9 K and the transition seems to be complete only at temperatures below 50 mK. This broad transition might be due to some disorder in the structure created by the low temperature phase transitions.
