Abstract
The pressure-temperature phase diagram of the organic superconductor (formula presented) is refined by performing measurements of the interlayer resistance (formula presented) and the longitudinal thermoelectric power (formula presented) In addition to refining the phase transitions previously discussed in the literature, the results show at least two new phase changes at high pressure. The complexity of the phase diagram suggests that the finite electric dipole moment of the asymmetric (formula presented) anions, which gives these anions an additional degree of freedom, should be taken into account in addition to their structural ordering.
