ionisation of amide hydrogen atoms is demonstrated by the preparation of a series of neutral complexes of quadridentate ligands containing two deprotonated amide groups. The other groups are either both primary amine, both secondary amine, or both thioether groups. The names of the ligands and the formulae of the complexes are NN′-di-(2-aminoethyl)malondiamide, Pd[CH2(CO·N·CH2·CH2NH2)2],3H2O, NN′-di-(3-ben
