Molybdenum dichloride dioxide is the inorganic compound with the formula MoO2Cl2.

Gaseous molybdenum dichloride dioxide is a monomer,[1] but upon condensation, it polymerizes to give a coordination polymer of uncertain structure.

With bulky anilines, it converts to the diimido complex MoCl2(NAr)2(dimethoxyethane).

This complex is the precursor to the Schrock carbenes of the type Mo(OR)2(NAr)(CH-t-Bu).

[4] Molybdenum difluoride dioxide exists as a sublimable white solid, in contrast to the dichloride.
