Abstract

A novel charge transfer complex containing of hexacyanoferrate (Fe(CN) 6) unit, which has been exhibited variety of magnetic topics in Prussian blue systems, was synthesized. X-ray analysis of the single crystal obtained by electrolysis of BEDT-TTF (ET) and hexacyanoferrate suggests that this complex contains ID magnetic hexacyanoferrate chain perpendicular to the conducting ET column. This significant structure implies that significant properties can be expected caused by the interaction between the spin momentum on d-electrons and a conducting π-electrons influenced vertically by the applied magnetic field. From the result of the electrical conducting measurement, it is suggested that is a semiconductor, with the activation energy and the conductivity at room temperature to be 0.113eV and 0.46S/cm. respectivity. Detailed X-ray analysis suggests that the occupancies of Fe and C elements in the ID hexacyanoferrate chain are 0.5, that of N element is 1.0.
