Redetermination of di-μ-hydrido-hexahydridotetrakis(tetrahydrofuran)dialuminium(III)magnesium(II)

Abstract

The structure of the title compound, [Mg(AlH4)2(C4H8O)4], has been redetermined at 150 K. The MgII ion is hexacoordinated to four tetrahydrofuran (THF) ligands, and two AlH4− anions through bridging H atoms. The Al—H distances are more precise compared to those previously determined [Nöth et al. (1995). Chem. Ber. 128, 999–1006; Fichtner & Fuhr (2002). J. Alloys Compd, 345, 386–396]. The molecule has twofold rotation symmetry.
