Abstract
(TTM-TTP)I3 which has been considered as the typical one-dimensional half-filled band system, has been critically restudied by structural and magnetic measurements. X-ray diffuse scattering study reveals the formation of 2kF CDW superstructure with the wave vector q1=(0, 0, 0.5) below 160 K of the metal-insulator transition temperature. Another structural modulation with q2= (0.5, 0, 0.5) is observed below 90–100 K. Modulated structure analysis using the q2 satellite reflections and the Bragg reflections shows the large displacement in I3 anion. Anomalies in χ, line width and g-value of ESR measurements which correspond to the structural anomaly, are also reported.
