The metal-to-ligand molar ratios are 1 : 1 in the complexes, which are 1 : 2 electrolytes for Pb(II), Cd(II) and Zn(II) and 1 : 3 electrolytes for La(III)eninfo:eu-repo/semantics/closedAccessmacrocyclic Schiff base complexes1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane1,10-bis(2-formylphenyl)-1,4,7,10-tetraoxadecane(+/-)-trans-1,2-diaminocyclohexaneSynthesis and characterisation of Schiff base macrocyclic Pb(II), Zn(II), Cd(II) and La(III) complexes by template reaction of (±)-trans-1,2-diaminocyclohexane with metal nitrates and salicylaldehyde derivativesArticle12766769N/AWOS:000273946700014Q32-s2.0-7394908476510.3184/030823409X12596000099172
