Lewis-Base Adducts of Main Group 1 Metal Compounds. V. Diaquabis(quinoline)lithium(I) Bromide Bis(quinoline)

Abstract

The title compound, an artefact of recrystallization of lithium bromide from improperly dried quinoline, has been characterized by a single- crystal X-ray structure determination. Crystals are triclinic, Pī , a 16.608(9), b 12.27(1), c 7.962(8)Ǻ, α 101.98(8),β 91.79(7),γ 92.27(6), Z 2; R was 0.058 for 2404 'observed' reflections. The cation is the first to be structurally defined for a [Li(OH2)2 (N-base)2]+ system; Li-O are 1.92(2), 1.93(2)Ǻ and Li-N 2.12(2), 2.14(2)Ǻ.
