Crystal structure of bis­(acetyl­acetonato-κ(2) O,O′)(tetra­hydro­furan-κO)(tri­fluoro­methane­sulfonato-κO)iron(III)

The mononuclear title complex, [Fe(CF(3)O(3)S)(C(5)H(7)O(2))(2)(C(4)H(8)O)] or [Fe(acac)(2)(OTf)(THF)] (acac = acetyl­acetonate; OTf = tri­fluoro­methane­sulfon­ate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe(3+) atom in a slightly distorted octa­hedral environment [Fe—O bond-length range = 1.9517 (11)–2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak inter­molecular C—H⋯O and C—H⋯F hydrogen-bonding inter­actions generate a two-dimensional supra­molecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis­(acetyl­acetonato)iron(III) complex.
