The mineralogical form of this compound is called tugarinovite, and is only very rarely found.

In TiO2 the oxide anions are close packed and titanium atoms occupy half of the octahedral interstices (holes).

[1] MoO2 can be prepared : Single crystals are obtained by chemical transport using iodine.

[3] Molybdenum dioxide is a constituent of "technical molybdenum trioxide" produced during the industrial processing of MoS2:[4][5] MoO2 has been reported as catalysing the dehydrogenation of alcohols,[6] the reformation of hydrocarbons[7] and biodiesel.

[9] Molybdenum dioxide has also been suggested as possible anode material for Li-ion batteries.
