Electrical, Magnetic and Spectroscopic Properties of (TTF)5Fe(NO3)3

Abstract

Tetrathiafulvalene, TTF, reacts with Fe (NO3). 9H20 to yield a dark purple charge-transfer compound with the formula (TTF)5Fe(NO3)3. effective magnetic moment at room temperature of 0.6 B. M. the temperature independent paramagnetism in the range 77-300 K, and the absence of an EPR signal attributable to iron, indicates low-spin iron (II) , with electron transfer from TTF. The g values of the parallel and perpendicular EPR lines, (T, g1, g1), (300 K, 2.007, 2.010), (77K, 2.009, 2.013), and the line widths indicate that the odd electron resides on, and is delocalized over several TTFs. The conductivity at room temperature is 17 S cm-1, and the temperature dependence of the resistivity indicates semiconducting behavior of a complex nature.... tetrathiafulvalene, magnetic moment, electrical conductivity, electroparamagnetic resonance, IRON(III) compound.
