The single crystal structural characterization of an array of t-butanol solvates of the lithium halides LiX, X ϭ Cl, Br, I is recorded. Two series have been identified, of LiX : t BuOH ratio 1:4 and 1:6, represented by the formulations [Li(HO t Bu) 4 ]X (X ϭ Cl, I; not isomorphous) and [Li(HO t Bu) 4 ]X·2 t BuOH (all X ϭ Cl, Br, I, also BH 4 ); isomorphous, triclinic P1, a ϳ 10.3, b ϳ 13, c ϳ 14.4 Å , α ϳ 73, β ϳ 70, γ ϳ 68°, Z ϭ 2. Li-O are 1.97 Å , in an environment of quasi-42m symmetry, the pair of O-Li-O angles trans to each other which contain the hydroxyl hydrogen atoms
