Tricarbonylbis(1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene)iron

A. Ahmida, U. Flörke and G. Henkel

Abstract top

In the title compound, [Fe(C11H20N2)2(CO)3], the Fe atom shows a distorted trigonal-bipyramidal geometry with three carbonyl and two carbene ligands. The latter have a cis arrangement, with a C-Fe-C angle of 90.60 (7)°. The Fe atom lies 0.007 (1) Å above the basal plane defined by two carbonyl and one carbene C atoms. The molecular structure is closely related to that of the isomolecular but not isotypic Ru complex with an identical cis arrangement, so, in general, bond geometries lie in expected ranges. In the crystal, C-H...O hydrogen bonds link the molecules into infinite zigzag chains extending along [010].

Experimental top

To a solution of 1,3-diisopropyl-4,5-dimethylimidazol-2-thione (850 mg, 4 mmol) in 30 ml THF was added K (420 mg, 1 mmol + 10% excess) and the mixture was refluxed under inert atmosphere for 4 h. After filtration and removal of K2S, Fe2(CO)9 (360 mg, 1 mmol) was added to the filtrate. The reaction mixture was stirred over night at room temperature. After removal of the solvent and subsequent drying in vacuum the residue was cyrstallized by diffusion of hexane into a concentrated toluene solution to give single-crystal of the title complex.

Refinement top

All Hydrogen atom positions were clearly derived from difference maps, then refined at calculated positions riding on the parent atoms with C—H 0.98 - 1.00 Å and isotropic displacement parameters Uiso(H) = 1.2U(Ceq) or 1.5U(–CH3). All CH3 hydrogen atoms were allowed to rotate but not to tip.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
