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.
