Abstract
Two novel LiCl·DMSO polymer structures were created by combining dry LiCl salt with dimethyl sulfoxide (DMSO), namely, catena-poly[[chloridolithium(I)]-μ-(dimethyl sulfoxide)-κ2
O:O-[chloridolithium(I)]-di-μ-(dimethyl sulfoxide)-κ4
O:O], [Li2Cl2(C2H6OS)3]
n
, and catena-poly[lithium(I)-μ-chlorido-μ-(dimethyl sulfoxide)-κ2
O:O], [LiCl(C2H6OS)]
n
. The initial synthesized phase had very small block-shaped crystals (<0.08 mm) with monoclinic symmetry and a 2 LiCl: 3 DMSO ratio. As the solution evaporated, a second phase formed with a plate-shaped crystal morphology. After about 20 minutes, large (>0.20 mm) octahedron-shaped crystals formed. The plate crystals and the octahedron crystals are the same tetragonal structure with a 1 LiCl: 1 DMSO ratio. These structures are reported and compared to other known LiCl·solvent compounds.
