Molybdenum(III) chloride is the inorganic compound with the formula MoCl3. It forms purple crystals.[1]
Synthesis and structure
Molybdenum(III) chloride is synthesized by the
reduction of molybdenum(V) chloride with hydrogen.[2] A higher yield is produced by the reduction of pure molybdenum(V) chloride with anhydrous tin(II) chloride as the reducing agent.[3]
Molybdenum trichloride exists as two
close-packing in its crystalline structure. The beta structure, however, exhibits hexagonal close packing.[4]
Ether complexes
Molybdenum trichloride gives a ether complexes MoCl3(thf)3 and MoCl3(Et2O)3. They are beige, paramagnetic solids. Both feature octahedral Mo centers. The diethyl ether complex is synthesized by reducing a Et2O solution of MoCl5 with tin powder.[5] Older procedures involve stepwise reduction involving isolation of the Mo(IV)-thf complex.[6]
salt metathesis reaction from MoCl3(thf)3:[7]
- 2 MoCl3(thf)3 + 6 LiOBu-t → Mo2(OBu-t)6 + 6 LiCl + 6 thf
