Metal sulfide and metal oxide alloys of the form Mo_1–xW_xS₂ and Mo_1–xW_xO₃ (0 ≤ x ≤ 1) are synthesized with varying nominal stoichiometries (x = 0, 0.25, 0.50, 0.75, and 1.0) by thermolysis of the molecular precursors MoL₄ and WS(S₂)L₂ (where L = S₂CNEt₂) in tandem and in various ratios. Either transition-metal dichalcogenides or transition-metal oxides can be produced from the same pair of precursors by the choice of reaction conditions; metal sulfide alloys of the form Mo_1–xW_xS₂ are produced in an argon atmosphere, while the corresponding metal oxide alloys Mo_1–xW_xO₃ are produced in air, both under atmospheric pressure at 450 °C and for only 1 h. Changes in Raman spectra and in powder X-ray diffraction patterns are observed across the series of alloys, which confirm that alloying is successful in the bulk materials. For the oxide materials, we show that the relatively complicated diffraction patterns are a result of differences in the tilt angle of MO₆ octahedra within three closely related unit cell types. Alloying of Mo and W in the products is characterized at the microscale and nanoscale by scanning electron microscopy–energy-dispersive X-ray spectroscopy (EDX) and scanning transmission electron microscopy–EDX spectroscopy, respectively.
