Morpholin als ambidenter Ligand

Abstract

AbstractMorpholine as Ambident LigandThe reaction of MeInCl2 with Li‐morpholinate [Li(Morph)] at 20 °C in THF gave after work‐up and recrystallization from diglyme the salt [Li(Diglyme){In3Me2Cl4(Morph)4}]·Diglyme (1). The treatment of the reaction mixture of MesInCl2/Li(Morph) with wet THF yield as only isolated compound the coordination polymer [Li6Cl6(HMorph)3] (2). Under similar conditions the reaction of InCl3 with Li(Morph) led after work‐up in wet THF to [Li(Diglyme)2][InCl4(HMorph)2] (3). 1 – 3 were characterized by NMR and IR spectroscopy as well as by X‐ray analysis. According to this, 1 contains the trinuclear anion [In3Me2Cl4(Morph)4]− in which one of the morpholinate ligands is coordinated via N atom to the In3+ ions, while the O atom belongs to the coordination sphere of the Li+ ion. In 2, LiCl forms a hexagonal heteroprismn, in which the morpholine molecules are responsible for a 3d network via coordination of both Lewis‐basic heteroatoms. 3 contains trans‐[InCl4(Hmorph)2]− ions, connected by hydrogen bonding along [011].
