Solvent influence on the formation of anhydrous mononuclear or multinuclear lanthanide complexes containing tetradentate Schiff-base ligands
Abstract
The syntheses, characterization, and crystal structures of six-coordinate mononuclear [bis-5,5′-(1,3-propanediyldiimino)-2,2-dimethyl-4-hexene-3-onato]lanthanum [bis(trimethylsilyl)amido][tetrahydrofuran], [bis-5,5′-(1,3-propanediyldiimino)-2,2-dimethyl-4-hexene-3-onato]neodymium [bis(trimethylsilyl)amido][tetrahydrofuran] and the dinuclear species tris[bis-5,5′-(1,3-propanediyldiimino)-2,2-dimethyl-4-hexene-3-onato]lanthanum are presented. The complexes are prepared from the reaction of homoleptic tris[(bistrimethylsilyl)amido]-lanthanum or -neodymium with the diprotic tetradentate
