Crystal structure of bis(μ2-tri-phenyl-acetato-κO:κO')bis(diisobutylaluminium).
Single crystals of the title compound, [Al(iBu)2(O2CCPh3)]2 or [Al2(C4H9)4(C20H15O2)2], have been formed in the reaction between tris-(tetra-hydro-furan)-tris-(tri-phenyl-acetato)-neodymium, [Nd(Ph3CCOO)3(THF)3], and triiso-butyl-aluminium, Al(iBu)3, in hexane followed by low-temperature crystallization (243 K) from the reaction mixture. The structure has triclinic (P ) symmetry at 120 K. The dimeric complex [Al(iBu)2(O2CCPh3-μ-κO:κO')]2 is located about an inversion centre. The tri-phenyl-acetate ligand displays a μ-κO:κO'-bridging coordination mode, leading to the formation of an octa-gonal Al2O4C2 core. The complex displays HPh⋯CPh inter-molecular inter-actions.
