N2 - A range of dialky a-hydroxyiminophosphonates R′C=N(OH)P(O)(OR)2, with substitueras of varying bulk (R = Et, R′ = Me L1, Et L2, Tr L3, 3-heptyl L4; R = iPr, R′ = Et L5, 3-heptyl L6; R = nBu, R′ = Pr L7) have been used to synthesise neutral metal complexes with nickel(n) [Ni(L1-3,5)Cl2], cobalt(II) [Co(L1-3,5)Cl2] and lanthanides (LaIII with L1,2,5, PrIII with L1,2,4,7, NdIII with L5, GdIII with L2,5 and DyIII with L 2,5) the charge being balanced by anionic ligands chloride or nitrate. Included in this range are two 3-heptyl derivatives which have not previously been reported. All the metal complexes have been fully characterised by elemental analysis, IR, electronic and NMR spectroscopy and mass spectrometry. X-Ray crystallography has been used to establish the structure of six key metal complexes and one of the free ligands (L3). Three different bonding modes have been established. The d-block metal chlorides consistently show symmetrical bidentate coordination in [ML2Cl2], the lanthanide chlorides [ML3Cl3] are all asymmetrically bidentate and monodentate coordination was observed in the neodymium nitrate complex [NdL5
2(NO3)3(H2O)].
