Yttrium 3,5-di-tert-butyl-catecholates supported by 2,6-diisopropylphenyl substituted β-diketiminate

Yttrium 3,5-di-tert-butyl-catecholates supported by 2,6-diisopropylphenyl substituted β-diketiminate
β-Diketiminato yttrium complex [LClY(μ-Cl)3YL(THF)] (L=2,6-iPr2C6H3-NC(Me)CHC(Me)N-2,6-iPr2C6H3) has been used for the preparation of non-solvated mixed-ligand compound [{LY(μ-3,5-Cat)}2] (1) by the salt metathesis reaction with potassium 3,5-di-tert-butyl-catecholate (3,5-CatK2). The dinuclear yttrium complex [{K(THF)}{LY(μ-3,5-Cat)3Y(THF)}] (2) has been found as an unexpected by-product of side reaction caused by the presence of an admixture of YCl3. Complex 1 has been fully characterized by a set of methods and its solid-state structure, along with that of by-product 2, has been determined by single-crystal X-ray diffraction analysis.
