By using a MoI2 precursor, a one-dimensional linear chain material, Mo6S3I6, was synthesized on a centimeter scale. As MoI2 can be used to form Mo6S3I6 through a gas-phase reaction, a larger amount of single crystals can be synthesized; moreover, these crystals are significantly longer than those synthesized by using Mo, S, and I powder. The synthesized Mo6S3I6 exhibited the characteristics of paramagnetic semiconductors with excellent thermal stability and a low bandgap. Furthermore, Mo6S3I6 can be separated into long nanometer-scale chains by a solution dispersion process.
