trans -Di-aqua-tetra-kis-(tetra-hydro-furan-κ O )iron(II) μ-carbonyl-tetra-deca-carbonyl-tetra-chlorido-μ-di-methyl-silanediolato-tetra-galliumtetra-iron(7 Ga - Fe )( Fe - Fe ) tetra-hydro-furan tetrasolvate.

The title compound, [Fe(C 4 H 8 O) 4 (H 2 O) 2 ][Fe 4 Ga 4 (C 2 H 6 O 2 Si)Cl 4 (CO) 15 ]·4C 4 H 8 O, consists of an iron(II) cation octa-hedrally coordinated by two water mol-ecules ( trans ) with four tetra-hydro-furans (THF) at equatorial sites. Two additional THF mol-ecules are hydrogen bonded to each of the water mol-ecules. 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.
