Abstract

Reaction of BrBu-n with LiBu-n(PMDETA) affords in high yield (PMDETA)LiBr (1) (PMDETA = Me2N-(CH2)2NMe(CH2)2NMe2), which forms dimeric aggregates in the solid. Crystals are triclinic, of space group [formula-omitted], with a = 14.887 (7) Å, b = 11.737 (6) Å, c = 8.631 (7) Å, α = 73.43 (6)°,β = 77.64 (5)°,γ = 80.93 (4)°, and Z = 2 dimers. The unit cell contains a pair of dimeric aggregates possessing “bridging” bromine atoms; the metal-halogen distances within each centrosymmetric aggregate are unsymmetric. Li-Br: 2.51 (1) and 3.20 (2) Å, aggregate 1; 2.57 (1) and 2.87 (1) Å, aggregate 2.
