A novel spin-crossover molecular conductor, [Fe(qnal)(2)] [Pd(dmit)(2)](5)center dot acetone, was prepared and characterized. The crystal structural analyses of both the low- and high-temperature phases revealed that the supramolecular pi-pi interactions between the spin-crossover Fe(qnal)(2) cations as well as the cation contraction play an important role in the uniaxial lattice deformation which will modulate the electrical conductivity of the conducting Pd(dmit)(2) layer.
