Preparation, Structure, and Density Functional Calculation of the Solvent-Separated Ion Pair [(H5C2)Al(OC6H5)3-···Li+···-(H5C6O)3Al(C4H9)]-[Li+(DME)3]
摘要:
Dimeric aluminum triethyl reacts in dimethoxyethane solution under argon with phenol and lithium n-butyl to the crystalline ethylaluminum-lithium-butylaluminum hexaphenolate salt with a solvent-separated tris(dimethoxyethane)lithium cation. Its structure determination at 130 It (monoclinic P2(1)/c with Z = 4, fw = 968.4, a = 1275.6(1) Angstrom, b = 1889.0(1) Angstrom, c = 2381.5(1) Angstrom, and beta = 104.59(1)degrees, wR(2) = 0.177) proves a linear arrangement of the {Al(O)...Li...(O)Al} centers. Density function calculations based on the structural coordinates provide information on the charge distribution.
