trans-Di-aqua-tetra-kis-(tetra-hydro-furan-κO)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)†à .
