In the title compound, [Mo(C5HF6O2)3], the unit cell is built up by three independent MoIII atoms located on two different threefold axes. The three independent mol­ecules are roughly identical and each MoIII atom is surrounded by three chelating hexa­fluoro­acetonate ligands in a three-bladed propeller-like arrangement, as observed in related compounds with acetyl­acetonate-type ligands. The structure of the title compound is very similar to the trigonal form of the CrIII analogue. However, the latter crystallizes in a higher-symmetry space group, P[\overline{3}]c1. Both crystals are twinned by merohedry with the same twin law ([\overline1][\overline1]0/010/00[\overline1]) in reciprocal space, but the symmetry of the Laue group in which it operates is different, [\overline{3}] to [\overline{3}]m for the title complex, and [\overline{3}]m to 6/mmm for the CrIII complex.
