trans-Di­aqua­tetra­kis­(tetra­hydro­furan-κO)iron(II) μ-carbonyl-tetra­deca­carbonyl­tetra­chlorido-μ-di­methyl­silanediolato-tetra­galliumtetra­iron(7 Ga–Fe)(Fe–Fe) tetra­hydro­furan tetrasolvate

The title compound, [Fe(C₄H₈O)₄(H₂O)₂][Fe₄Ga₄(C₂H₆O₂Si)Cl₄(CO)₁₅]·4C₄H₈O, consists of an iron(II) cation octa­hedrally coordinated by two water mol­ecules (trans) with four tetra­hydro­furans (THF) at equatorial sites. Two additional THF mol­ecules are hydrogen bonded to each of the water mol­ecules. The dianion of the title compound is an organometallic butterfly complex with a dimethyl siloxane core and two iron-gallium fragments. The lengths of the iron to gallium metal–metal bonds range from 2.3875 (6) to 2.4912 (6) Å.

Structure description

The accidental incorporation of silicone vacuum grease into chemical reactions has produced several unique compounds that contain di­methyl­siloxane fragments (Haiduc, 2004). In our study of the chemical reactivity of digallium(II) dichloride with transition-metal clusters we now report the formation of the title compound, which contains a di­methyl­siloxane-gallium-iron butterfly dianion cluster (Li & Rauchfuss, 2016). The Ga₂Cl₄ solution, see Synthesis and crystallization section, used in this reaction was contaminated with silicone vacuum grease. This inter­action produced a gallium-siloxane inter­mediate that has yet to be identified. The vacuum grease is also thought to be the source of water that is observed coordinating to the iron(II) cation.

The dianion of the title compound has a dimethyl siloxane entity in which the oxygen atoms are binding to the gallium atoms. There are two types of gallium atoms in this cluster: two belong to GaCl₂ fragments and two gallium atoms are bound only to oxygen or iron atoms (Fig. 1). The distances between Ga1—Ga2 and Ga3—Ga4 are 2.9476 (5) Å and 2.9736 (6) Å, respectively. These values are much longer than 2.406 Å observed for Ga₂Cl₄·2(1,4-dioxane) (Beamish et al., 1979), indicating there are no metal–metal bonding inter­actions between the pairs of gallium atoms. The iron–gallium and iron–iron bond lengths of the dianion are listed in Table 1. The dication of the title compound is an octa­hedral coordination complex, trans-[Fe(H₂O)₂(THF)₄]²⁺. Each of the water mol­ecules is hydrogen bonded to two additional THF mol­ecules (Table 2) in the crystal structure (Fig. 2).

Synthesis and crystallization

All manipulations were conducted using inert atmosphere techniques. A stock solution of Ga₂Cl₄ was produced by the reaction of Ga (5.496 g, 78.83 mmol) with GaCl₃ (5.01 g, 28.4 mmol) in 150 ml of toluene. The mixture was heated to reflux for 24 h then cooled to 25°C. Note: after the title compound's structure was determined, it was noted visually that a small amount of silicone vacuum grease had contaminated this stock solution.

In a 150 ml Schlenk flask, Fe₃(CO)₁₂ (0.493 g, 0.979 mmol) in 35 ml of toluene was combined with 10 ml of the Ga₂Cl₄ stock solution. The reaction flask was refluxed for 2 h. During this time the reaction mixture changed from a deep green/black color to dark orange. The mixture was cooled to room temperature, and the solution was deca­nted away from the residue into a new Schlenk flask, 20 ml of THF were added to this solution. The solution was cooled to −15°C and orange crystals were observed after 72 h. A single crystal was coated with NVH oil and mounted on a MiTeGen loop under a stream of argon gas then cooled to −70°C for data collection.

Refinement

Crystal data, data collection, and structure refinement details are summarized in Table 3. The THF mol­ecules were refined using the SAME restraint. The water mol­ecules (O51, O52) bound to Fe5 were refined with the DFIX and SADI (same distances with standard deviation of 0.01 Å) restraints. Two THF mol­ecules hydrogen bonding to the water mol­ecules were split into residues 6 and 7 and residues 9 and 10, respectively, and modeled for disorder. The occupancy values of each residue pair were 48.6/51.4 and 48.4/51.6, respectively.

Special details

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