X-ray diffraction and QTAIM calculations of the non-covalent intermolecular fluorine-fluorine interactions in tris(trifluoroacetylacetonato)-manganese(III)

An X-ray study was conducted on tris(trifluoroacetylacetonato)-manganese(III). The two different molecules in the unit cell exhibit a distorted octahedral geometry and moderate compression Jahn–Teller distortion respectively. A number of F⋯H and F⋯F intermolecular interactions were observed in the packing of the crystals in the solid state. The crystal packing effects could lead to the observed compressed Jahn–Teller distortion, instead of the...
