Abstract

The asymmetric unit of the title compound, μ-biphenyl-4,4'-di-sulfonato-bis-(aqua-lithium), [Li₂(C₁₂H₈O₆S₂)(H₂O)₂] or Li₂[Bph(SO₃)₂](H₂O)₂, consists of an Li ion, half of the diphenyl-4,4'-di-sulfonate [Bph(SO₃ ^-)₂] ligand, and a water mol-ecule. The Li ion exhibits a four-coordinate tetra-hedral geometry with three oxygen atoms of the Bph(SO₃ ^-)₂ ligands and a water mol-ecule. The tetra-hedral LiO₄ units, which are inter-connected by biphenyl moieties, form a layer structure parallel to (100). These layers are further connected by hydrogen-bonding inter-actions to yield a three-dimensional network.

Keywords: Li ion; crystal structure; hydrogen bonding.
