Access to the structures of fluoromagnesium compounds:: synthesis and structural characterization of the β-diketiminato magnesium fluoride [{CH(CMeNAr)2}Mg(μ-F)(THF)]2•toluene

beta-Diketiminato magnesium fluoride [{CH(CMeNAr)(2)}Mg(mu-F)(THF)](2)(.)toluene (Ar = 2,6-i-Pr2C6H3, 2(.)toluene) was synthesized. The molecular structure of 2 revealed for the first time, the double fluoro bridge feature between the two magnesium atoms with a typical Mg-F bond length (average 1.95 Angstrom).
