Chemical compound
Molybdenum(VI) chloride
is the
inorganic compound
with the formula MoCl
6
. It is a black diamagnetic solid. The molecules adopt an octahedral structure as seen in β-
tungsten(VI) chloride
.

Preparation and reactions
[
edit
]
Molybdenum(VI) chloride is prepared from the
molybdenum hexafluoride
with excess
boron trichloride
:
- MoF
6
+ 3 BCl
3
→ MoCl
6
+ 3 BF
2
Cl
It is unstable at room temperature with respect to
molybdenum(V) chloride
and decomposition completes within several days:
- 2 MoCl
6
→ [MoCl
5
]
2
+ Cl
2
The treatment of
MoF
6
with
bismuth trichloride
also produces MoCl
6
.
