A new charge transfer salt (TCN-DBTTF)[Fe(H2O)6][FeBr4]3 (1) (TCN-DBTTF:tetracyanodibenzotetrathiafulvalene) has been synthesized by electrocrystallization and structurally characterized. The compound crystallizes in the monoclinic space group C2/c, M = 1694.91, a = 35.759(3) Å, b = 9.9966(6) Å, c = 12.1129(10) Å, β = 98.350(7)°, V = 4284.1(6) Å3 and Z = 4. The compound is composed of three types of paramagnetic spin carriers: oxidized TCN-DBTTF radicals (S = 1/2), [Fe(H2O)6]2+ cations (S = 2) and [FeBr4]− anions (S = 5/2). Due to the specific crystal packing, an electrical conductivity at room temperature in the order of only 10−7 S cm−1 is observed and magnetic measurements reveal overall antiferromagnetic interactions among the three different spin centers.Figure optionsDownload as PowerPoint slide
A charge transfer salt (TCN-DBTTF)[Fe(H2O)6][FeBr4]3 was synthesized by electrocrystallization and structurally characterized. As a result of the specific crystal packing, the compound shows a low electrical conductivity in the order of 10−7 S cm−1 and the magnetic measurements exhibit overall antiferromagnetic exchange interactions among the three different spin carriers.Figure optionsDownload as PowerPoint slide
