Solvation structure of Li+ in highly concentrated LiTFSA–DMSO solutions studied by means of neutron diffraction with 6Li/7Li isotopic substitution method
Abstract Time-of-flight neutron diffraction measurements for 6Li/7Li isotopically substituted 20 mol% *LiTFSA–DMSO-d6 solutions have been carried out to investigate the solvation structure of Li+ in a highly concentrated DMSO solution. Structural information on the nearest-neighbor Li+…DMSO interaction has been determined by using the least squares fitting procedure of the observed difference interference term, ΔLi(Q). It has been revealed that 4.1(2) DMSO molecules are involved in the first solvation shell of Li+ in the present solutions. The nearest-neighbor Li+…ODMSO distance and bond angle, ∠Li+…ODMSO = SDMSO, have been determined to be 1.96(3) Å and 138(15)°, respectively.
