Molybdenum is a transition metal, Molybdenum has several oxidation states, the most stable being +4 and +6 (bolded in the table). The chemistry and the compounds show more similarity to those of tungsten than that of chromium. An example is the instability of molybdenum (III) and tungsten (III) compounds as compared with the stability of the chromium (III) compounds.

Single phase tungsten–molybdenum mixed oxide films (W1−xMoxO3) were successfully synthesized by automated parallel electrodeposition, and distinct structural changes were observed as a function of composition.
