Abstract

We report a study of the temperature dependence of the

2 k_{F}

instability in the one-dimensional conductor

K_{2}

{(CN)}_{4}

{Br}_{0.30}

{\cdot 3 D}_{2}

O using a neutron scattering technique. Whereas the extra scattering at room temperature has a one-dimensional character corresponding to a periodicity along the

C

axis of 6.66 Pt-Pt spacings, below 220 K it indicates the development of a three-dimensional superlattice structure with a new unit cell

2 a \times 2 a \times 6.66 c

. However, this transition seems to be incomplete, in the sense that the coupling between adjacent chains does not achieve long-range order.
