Abstract
The structure of the title compound, [Mg(AlH(4))(2)(C(4)H(8)O)(4)], has been redetermined at 150 K. The Mg(II) ion is hexa-coordinated to four tetra-hydro-furan (THF) ligands, and two AlH(4) (-) 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 mol-ecule has twofold rotation symmetry.
