Bis­(di­meth­oxy­ethane-1κ(2) O,O′)penta­kis­(1,1,1,3,3,3-hexa­fluoro­propan-2-olato)-2κ(3) O,3κ(2) O-μ-hy­droxido-1:3κ(2) O-μ(3)-oxido-1:2:3κ(3) O-magnesiumdialuminium

Partial hydrolysis of a sample of [Mg(dme)(3)][Al(hfip)(4)](2) crystals led to the formation of the title complex, [Mg(dme)(2){HOAl(hfip)(2)OAl(hfip)(3)}] (dme = di­meth­oxy­ethane and hfipH = hexa­fluoro­iso­propanol) or [Mg(C(4)H(10)O(2))(2)O(OH)Al(2)(C(3)HF(6)O)(5)]. The magnesium cation exhibits a distorted octa­hedral coordination with two bidentate di­meth­oxy­ethane mol­ecules and a dinuclear aluminate anion, coordinated to Mg(2+) via oxido and hydroxido units. The anion is an oxido-bridged species, [HOAl(hfip)(2)(μ-O)Al(hfip)(3)](2–), with one Al(3+) cation tetra­hedrally coordinated by an oxido (O(2–)) anion, a hydroxido anion, and two hfip groups, whereas the second Al(3+) cation is coordinated by the oxido anion and three hfip groups.
