Abstract
Lanthanide complexes of dialkyl α-hydroxyiminophosphonates (RO)2P(O)C(R′)N(OH)(L1–L3), where R = Et or Pri and R′= Me or Et, have been prepared for the first time; the crystal structures of two complexes of L1(R = Pri, R′= Et) have been determined, showing nine-co-ordination geometry in both cases with asymmetric bidentate ligands in [PrL13Cl3] and monodentate bonding in [NdL12(NO3)3(H2O)] demonstrating that the ambivalent nature of the new ligands allow formation of neutral complexes.
