Synthesis and structure of a Zwitterionic Nd complex containing aminophenoxide ligands

Research output: Contribution to journal › Article › peer-review

Abstract

In the course of attempting to prepare molecular precursors to lanthanide-aluminum oxide materials the unique Zwitterionic complex, Nd(H₂L)₃(CF₃SO₃)₃ (1) was discovered (L = [2,4-(¹Bu)₂-6- (CH₂N(i)Pr)PhO]). In the crystal structure of(1) the three-triflate groups and the three oxygens of the aminophenoxide ligand (H₂L) coordinate the Nd atom. To maintain charge balance the three ligands are protonated at the amine nitrogens. This explains the fact that the ligand is monodentate and does not displace one (or more) of the triflate groups to form a chelated cation. Both hydrogens of the ammonium groups are hydrogen-bonded to oxygens of the triflates.
