Tris(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato-κ(2) O,O′)molybdenum(III)
In the title compound, [Mo(C(5)HF(6)O(2))(3)], the unit cell is built up by three independent Mo(III) atoms located on two different threefold axes. The three independent molecules are roughly identical and each Mo(III) atom is surrounded by three chelating hexafluoroacetonate ligands in a three-...

Sumario: | In the title compound, [Mo(C(5)HF(6)O(2))(3)], the unit cell is built up by three independent Mo(III) atoms located on two different threefold axes. The three independent molecules are roughly identical and each Mo(III) 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 Cr(III) analogue. However, the latter crystallizes in a higher-symmetry space group, P [Image: see text] c1. Both crystals are twinned by merohedry with the same twin law ([Image: see text] [Image: see text]0/010/00[Image: see text]) in reciprocal space, but the symmetry of the Laue group in which it operates is different, [Image: see text] to [Image: see text] m for the title complex, and [Image: see text] m to 6/mmm for the Cr(III) complex. |
