The van Hove singularity can enhance structural and magnetic instabilities, which can compete with superconductivity. Evidence for such instabilities, including dynamical fluctuations and pseudogaps, is presented.

β¦ Synopsis
The competition between different anion orderings, which influences the electronic properties, is illustrated with 3 examples of recent X-ray studies of the alloy (TMTSF) 2 (CI04) I_Γ (ReO4)x, (TMTSF) 2 ReO 4 under pressure and (TMTSF) 2 PF2O 2.

We discuss the role of Coulombic repulsion in organic superconductors exhibiting quasi-one-dimensional transport properties. A recent investigation in high magnetic fields shows that the charge localization occurring at low temperature in a 1-D half-fillled band is suppressed by the 1-D to 2-D (3-D)
