N2 - Reaction of N-methylthiomorpholine hydroiodide with LiAlH4 in OEt2 yielded the Lewis-base adduct of alane, AlH3·NMe(CH2CH2)2S 1, which is monomeric in benzene as the N-donor species. Thiomorpholine with H3Al·NMe3 also in OEt2 afforded the metallated species {AlH2[μ-N(CH2CH2)2S]}2 2; in the solid-state dimers arising from bridging amido centres are weakly associated via intermolecular Al ⋯ S interactions at 3.22(3) Å. Treatment of 2-diethylaminoethanethiol hydrochloride with LiMH4 (M = Al or Ga) in OEt2 or tetrahydrofuran generated the five-co-ordinate species MH(SCH2CH2NEt2)2 (M = Al 3 or Ga 4), authenticated by X-ray crystallography as isostructural, chiral five-co-ordinate species in the solid, the N-donor groups occupying apical positions of trigonal-bipyramidal metal centres.
