Bis-(di-meth-oxy-ethane-1κ 2 O , O ')penta-kis-(1,1,1,3,3,3-hexa-fluoro-propan-2-olato)-2κ 3 O ,3κ 2 O -μ-hy-droxido-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 = di-meth-oxy-ethane and hfipH = hexa-fluoro-iso-propanol) 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 octa-hedral coordination with two bidentate di-meth-oxy-ethane mol-ecules 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 tetra-hedrally 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.
