title: Lithium difluoro-(oxalato)borate tetra-methyl-ene sulfone disolvate.
abstract: The title compound, Li(+)·C(2)BF(2)O(4) (-)·2C(4)H(8)O(2)S, is a dimeric species, which resides across a crystallographic inversion center. The dimers form eight-membered rings containing two Li(+) cations, which are joined by O(2)S sulfone linkages. The Li(+) cations are ligated by four O atoms from the anions and solvent mol-ecules, forming a pseudo-tetra-hedral geometry. The exocyclic coordination sites are occupied by O atoms from the oxalate group of the difluoro-(oxalato)borate anion and an additional tetra-methyl-ene sulfone ligand.
