Crystal structure of bis(μ(2)-tri­phenyl­acetato-κO:κO′)bis(diisobutylaluminium)

Single crystals of the title compound, [Al(iBu)(2)(O(2)CCPh(3))](2) or [Al(2)(C(4)H(9))(4)(C(20)H(15)O(2))(2)], have been formed in the reaction between tris­(tetra­hydro­furan)­tris­(tri­phenyl­acetato)­neodymium, [Nd(Ph(3)CCOO)(3)(THF)(3)], and triiso­butyl­aluminium, Al(iBu)(3), in hexane followed by low-temperature crystallization (243 K) from the reaction mixture. The structure has triclinic (P [Image: see text]) symmetry at 120 K. The dimeric complex [Al(iBu)(2)(O(2)CCPh(3)-μ-κO:κO′)](2) is located about an inversion centre. The tri­phenyl­acetate ligand displays a μ-κO:κO′-bridging coordination mode, leading to the formation of an octa­gonal Al(2)O(4)C(2) core. The complex displays H(Ph)⋯C(Ph) inter­molecular inter­actions.
