37. 4 in this paper is also an organic superconductor having the θ-type molecular arrangement, whose transition temperature is 8K under uniaxial strain. The salt has a metal-insulator transition at 250 K, which is speculated to be a charge-ordered transition. In this discussion, we exclude this salt since a different kind of molecule is considered to affect the on-site potential U, which is one of the important parameters in quarter-filled systems.
