The processing of most one-dimensional nano-materials such as carbon-nanotubes is hampered by the fact that they are insoluble. Here we show how a significant portion (≈12wt%) of the as-produced Mo<sub>6</sub>S<sub>4.5</sub>I<sub>4.5</sub> nanowires is stably dispersed in isopropanol as small diameter nanowire bundles. Sedimentation studies, performed combining experiments and theory, show the presence of three phases in the raw material: impurity material, insoluble and soluble nanowire bundles. A purification procedure is also discussed. The three phases has been characterized by UV-Vix-IR spectroscopy and XPS showing their intrinsic diversity.
