BaVS3 is an unusual 3d1 quasi-one dimensional (1D) correlated system presenting an interplay of charge, orbital and spin degrees of freedom. At TMI=70K, BaVS3 undergoes a metal-insulator transition whose origin is still a matter of controversy. We show that this transition is associated with a structural modulation preceded by an extended temperature range of 1D lattice fluctuations. We have refined the superstructure and showed that it corresponds to a complex modulation of the V bonds leading to the formation of an Unconventional Charge Density Wave (CDW) ground state.
