While silicon is a crucial semiconducting material, solution-based synthetic approaches for unsaturated silicon-rich molecules require less efficient multi-step syntheses. Here, the authors report access to soluble, polyhedral Si9 clusters from the binary phase K12Si17, which contains both [Si4]4− and [Si9]4− clusters.
