Abstract
Abstract The X-ray structure of 1-lithio-2-methoxybenzene (2-methoxyphenyllithium) has been determined at 298 K by single crystal X-ray techniques. The compound crystallizes in the triclinic system with spacegroup P 1¯. Cell dimensions: a 8.889(2),b 11.710(5),c 12.941(3)A, α 80.47(3), β 84.22(2), γ 82.37(3)°. The structure has been refined toR(F) = 0.069 for 1300 unique observed reflections withI ≥ 2.5σ(I). Each unit-cell contains two centrosymmetrically related tetrameric units which show Li ⋯ HC interactions with each other. Its structure in solution has been determined by NMR spectroscopy and association measurements. The influence of various Lewis bases on the solution structure has been studied.
