Lithium trifluoromethanesulfonate acetonitrile adduct

N. R. Brooks, W. A. Henderson and W. H. Smyrl

Abstract: The title compound, poly[[(acetonitrile)lithium(I)]--triflato], [Li(CF₃O₃S)(C₂H₃N)], was synthesized by reaction of LiCF₃SO₃ with CH₃CN and is found to exist as a one-dimensional polymer in the solid state. Each Li⁺ cation is tetrahedrally coordinated by three oxygen donors from three different CF₃SO₃^- anions [Li-O = 1.925  (3), 1.926  (3) and 1.940  (2)  Å] and one CH₃CN nitrogen donor [Li-N = 2.042  (3)  Å]. The unit cell has a angle of 90.064  (3)°, but the Laue symmetry is 2/m. As a result of this, the crystals exist as pseudo-merohedral twins related by the twin law (00/00/001).
