Abstract

The title compound consists of an octahedral iron(II) cation coordinated to two water molecules (trans) with four tetrahydrofuran (THF) ligands. 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 dimethylsiloxane core and two iron-gallium fragments.

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.
