Cluster structure. (a) Powder XRD pattern of the Na2[Mo3S13] and (NH4)2[Mo3S13] along with the ICDD 04-021-7028 reference pattern of the ammonium salt, (b) overlayed ATR-FTIR and Raman spectra of the Na2[Mo3S13] powder featuring characteristic molecular vibrations and the corresponding ranges, (c) molecular model of the [Mo3S13]2– compared to the edge structure of the MoS2 sheet, similar bonding motifs are highlighted; and (d) UV–Vis absorption spectrum of the 0.025 mM Na2[Mo3S13] solution in water and water/methanol featuring a characteristic absorption band.
