AbstractTwo polymorphic hybrid organic-inorganic bilayered magnetic conductors (BEDT-TTF)(3)(FeCl4)(2) (I and II) (BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene) were obtained by the diffusion method. I crystallizes in a monoclinic system with cell parameters: a = 55.9187(7) angstrom, b = 6.7424(1) angstrom, c = 14.9057(3) angstrom, beta = 10 1.056(1)degrees, 5515.5(2) angstrom(3), Z = 4, and C2/c at 290 K, and it transforms to a triclinic system at 220 K: a = 13.4440(2) angstrom, b = 14.6761(2) angstrom, c = 28.1529(5) angstrom, alpha = 100.738(1)degrees, beta = 96.875(1)degrees, gamma = 90.017(1)degrees, V = 5416.8(2) angstrom(3), Z = 4 and P (1) over bar which is stable to 110 K. II crystallizes in a triclinic system with cell parameters: a = 6.7396(3) angstrom, b = 9.9640(5) angstrom, c = 21.132(1) angstrom, alpha = 79.536(2)degrees, beta = 81.032(2)degrees, gamma = 81.066(3)degrees, V = 1367.3(1) angstrom(3), Z = 1, and P (1) over bar 290 K. They both contain two donor layers having formal charge of BEDT-TTF+0.5 in layer-A and BEDT-TTF+1.0 in layer-B. The donor arrangements in layer-A are delta-type in I and beta'-type in II, while the donor arrangements in layer-B and anion arrangements in I and II are also different. Layer-A is separated from layer-B by FeCl4-. The energy band calculation indicates a Peierls-like metal-insulator transition in the transverse direction at 220 K in I (sigma(300K) = 120 S.cm(-1)), and a Mott insulating state in II (sigma(300K) = 10(-2) S.cm(-1) and E-alpha = 0.2 eV). The presence of pi-d interactions between donors and anions results in the magnetic anomalies observed at 4.8 K in I and 2.7 K in II.
