Molybdenum oxytetrachloride is the inorganic compound with the formula MoOCl4. This thermally unstable, dark green solid is used to prepare other complexes of molybdenum. It adopts a square pyramidal structure of C4v symmetry. As for other Mo(VI) compounds, it is diamagnetic. It decomposes thermally to MoOCl3.

Preparation

It is prepared by treating molybdenum pentachloride with oxygen.[1] It also arises by chlorination of molybdenum trioxide:[2]

MoO3 + 2 SOCl2 → MoOCl4 + 2 SO2
