Bis(1,2-dimethoxyethane)-1κ²O,O′;3κ²O,O′-tetra­kis­(μ-1,1,1,3,3,3-hexa­fluoro-2-methyl­propan-2-olato)-1:2κ⁴O:O;2:3κ⁴O:O-1,3-dilithium-2-magnesium

The title compound, [Li₂Mg(C₄H₃F₆O)₄(C₄H₁₀O₂)₂], forms as a white crystalline powder by-product of the reaction of lithium 1,1,1,3,3,3-hexa­fluoro-2-methyl-2-propoxide with Mo(N-2,6-Me₂—C₆H₃)(CHCMe₂Ph)(O₃SCF₃)₂·2DME (DME is 1,2-dimethoxyethane) contaminated with MgCl₂. The crystal structure of this compound contains half a mol­ecule in the asymmetric unit, with a twofold rotation axis through the central Mg²⁺ cation. The four 1,1,1,3,3,3-hexa­fluoro-2-methyl­propan-2-olate ligands serve as bridging ligands connecting the Li⁺ and Mg²⁺ cations. The Li⁺ cation is additionally stabilized by a DME ligand. This results in a distorted tetra­hedral ligand field around both the Mg²⁺ and Li⁺ cations.
