Abstract

The crystal structure of lithium bis(trifluoromethanesulfonimide) [LiN(CF3SO2)2] has been solved from X-ray powder diffraction data and refined by the Rietveld method. The salt crystallises in the orthorhombic system, space group Pnaa, a = 9.6351(2) angstrom, b = 5.4154(1) angstrom, c = 16.2639(3) angstrom. The anion, previously uncharacterised crystallographically, has two-fold symmetry around the nitrogen atom, with short [1.56(1) angstrom] S-N distances and a large S-N-S angle [129(1)-degrees]. This is consistent with other similar salts and suggests a high degree of double-bond character and delocalisation around N. Li+ is tetrahedrally coordinated by four oxygens from four neighbouring anions.
