T1 - Synthesis of the first lanthanide complexes of dialkyl α-hydroxyiminophosphonates; ambivalent ligand bonding in the PrIII and NdIII complexes of diisopropyl α-hydroxyiminopropylphosphonate (L1), [PrL1
3Cl3] and [NdL1
2(NO3)3(H2O)]

N2 - 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 [PrL3
1Cl3] and monodentate bonding in [NdL2
1(NO3)3(H2O)] demonstrating that the ambivalent nature of the new ligands allow formation of neutral complexes.
