Bis(1,2-dimethoxyethane)-1?(2)O,O';3?(2)O,O'-tetra-kis-(?-1,1,1,3,3,3-hexa-fluoro-2-methyl-propan-2-olato)-1:2?(4)O:O;2:3?(4)O:O-1,3-dilithium-2-magnesium.


ABSTRACT: The title compound, [Li(2)Mg(C(4)H(3)F(6)O)(4)(C(4)H(10)O(2))(2)], forms as a white crystalline powder by-product of the reaction of lithium 1,1,1,3,3,3-hexa-fluoro-2-methyl-2-propoxide with Mo(N-2,6-Me(2)-C(6)H(3))(CHCMe(2)Ph)(O(3)SCF(3))(2)·2DME (DME is 1,2-dimethoxyethane) contaminated with MgCl(2). The crystal structure of this compound contains half a mol-ecule in the asymmetric unit, with a twofold rotation axis through the central Mg(2+) cation. The four 1,1,1,3,3,3-hexa-fluoro-2-methyl-propan-2-olate ligands serve as bridging ligands connecting the Li(+) and Mg(2+) cations. The Li(+) cation is additionally stabilized by a DME ligand. This results in a distorted tetra-hedral ligand field around both the Mg(2+) and Li(+) cations.
