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
Silver electroplating baths having certain sulfide compounds and methods of electrodepositing a silver-containing layer using these baths are disclosed. Such electroplating baths are useful to provide silver-containing solder deposits having reduced void formation and improved within-die uniformity.
