Morpholin als ambidenter Ligand

Morpholine as Ambident Ligand The reaction of MeInCl 2 with Li‐morpholinate [Li(Morph)] at 20 °C in THF gave after work‐up and recrystallization from diglyme the salt [Li(Diglyme){In 3 Me 2 Cl 4 (Morph) 4 }]·Diglyme ( 1 ). The treatment of the reaction mixture of MesInCl 2 /Li(Morph) with wet THF yield as only isolated compound the coordination polymer [Li 6 Cl 6 (HMorph) 3 ] ( 2 ). Under similar conditions the reaction of InCl 3 with Li(Morph) led after work‐up in wet THF to [Li(Diglyme) 2 ][InCl 4 (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 [In 3 Me 2 Cl 4 (Morph) 4 ] − in which one of the morpholinate ligands is coordinated via N atom to the In 3+ 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 ‐[InCl 4 (Hmorph) 2 ] − ions, connected by hydrogen bonding along [011].
