Synthesis of highly soluble yttrium–salen complexes and the X-ray structure of N,N′-bis(3,5-di-tert-butylsalicylidene)ethylenediamine-[bis(dimethylsily)amido]yttrium

Abstract

N,N′-Bis(3,5-di-tert-butylsalicylidene)ethylenediamine H₂L reacts with [Y{N(SiHMe₂)₂}₃(thf)₂] in thf–hexane at ambient conditions to afford monomeric [YL{N(SiHMe₂)₂}(thf)], the X-ray structure determination of which reveals a strongly bent coordination mode of the anionic salen derived ligand.
