Abstract

Using newly developed X-ray low temperature camera, 4kF periodic modulation was observed in organic quasi one-dimensional (Q1D) compounds (DMe-DCNQI)2Ag(abbreviated as DMe) and (DI-DCNQI)2Ag (abbreviated as DI). From 4kF satellite reflection intensity distribution in q-space, periodic molecular displacement in DMe and periodic molecular deformation possibly related with molecular valence ordering in DI were found. These modulation patterns suggest occurrence of 4kF bond CDW in DM and 4kF site CDW in DI. The 4kF site CDW possibly caused by a marked intersite correlation V, can be interpreted as a Wigner crystal.
