Crystal structure of bis(μ-tri-phenyl-acetato-κ:κ')bis(diisobutylaluminium).

Single crystals of the title compound, [Al(iBu)(OCCPh)] or [Al(CH)(CHO)], have been formed in the reaction between tris-(tetra-hydro-furan)-tris-(tri-phenyl-acetato)-neodymium, [Nd(PhCCOO)(THF)], and triiso-butyl-aluminium, Al(iBu), in hexane followed by low-temperature crystallization (243 K) from the reaction mixture. The structure has triclinic ( ) symmetry at 120 K. The dimeric complex [Al(iBu)(OCCPh-μ-κ:κ')] is located about an inversion centre. The tri-phenyl-acetate ligand displays a μ-κ:κ'-bridging coordination mode, leading to the formation of an octa-gonal AlOC core. The complex displays H⋯C inter-molecular inter-actions.
