Bis(³-indenyl)bis(tetrahydrofuran)magnesium(II)

H. Gritzo, F. Schaper and H.-H. Brintzinger

Abstract: In the crystal structure of the title compound, [Mg(C₄H₈O)₂(C₉H₇)₂], the two indenyl ligands are bound to the Mg atom in a manner intermediate between ¹- and ³-coordination; the latter is untypical, as it includes one of the ring-sharing C atoms. The O-Mg-O angle [101.01°] is larger than for any other magnesocene-(THF)₂ adduct (THF is tetrahydrofuran). A crystallographic C₂ axis bisects the O-Mg-O angle.
