Laser evaporation of MoS2 nanoflakes gives negatively charged magic number clusters of compositions Mo13S25 and Mo13S28, which are shown to have closed-cage structures. The clusters are stable and do not show fragmentation in the post-source decay analysis even at the highest laser powers. Computations suggest that Mo13S25 has a central cavity with a diameter of 4.5 Å. The nanosheets of MoS2 could curl upon laser irradiation, explaining the cluster formation.
