Abstract

Three new charge transfer salts of BEDT-TTF and TTF with the counter ions [M(NCS)4(C9H7N)J~ (M = Cr, Fe; C9H7N = isoquinoline) are described. The materials are prepared by standard electrocrystallisation techniques. The nature of the anion is verified in the crystal structure of the salt [C9H8N][Cr(NCS)4(C9H7N)]-C,2H24O6-H2O which is used as the electrolyte when M = Cr. All of the charge transfer salts display long range ferrimagnetic order originating from the interaction between M (5=3/2 or 5= 5/2) and the donor (5= 1/2). The measured critical temperatures are 4.2 K (BEDT-TTF, M = Cr), 4.5 K (BEDT-TTF, M = Fe) and 8.9 K (TTF, M = Cr). Each of the compounds also shows a modest magnetic hysteresis of 338, 18 and 75 Oe for BEDT-TTF salts of M = Cr, Fe and the TTF salt of Cr, respectively. © The Royal Society of Chemistry 2000.
