摘要：

Tight-binding band structure calculations for the room temperature crystal structure of the new family of (BEDT-TTF)(4)M[Fe(CN)(5)NO](2) (M = Na, K, Rb, NH4, Cs, Tl) salts are reported. It is shown that the Fermi surface of these salts contains two contributions: (a) a strongly warped non-nested open part and (b) a contribution which can be open or closed depending on minor changes in the donor-donor interactions which in either case exhibits well-nested portions. Because of these features, the pressure dependence of both the magnetoresistance measurements and the possible occurrence of density wave instabilities would be very interesting to study.
