✦ Synopsis

XPS. and ^1^H‐NMR. spectra of 1,3‐diaryltriazenes complexes of Hg(II)

The core binding energies C 1__s__, N 1__s__, Hg 4__f__~7/2~, Hg 4__f__~5/2~ in 7 symmetrical p‐substituted 1,3‐diphenyltriazenes complexes of Hg(II) have been measured by XPS. Within the limits of experimental error (± 0.2 eV) only one N 1__s__ signal could be detected. This indicates the equivalence of the 3 N‐atoms. Invariance of C 1__s__, N 1__s__, Hg 4__f__~7/2~, Hg 4__d__~5/2~ signals with the para substituents on the phenyl ring is explained on the basis of ionic character in the Hg, N bond. These results are corroborated by the ^1^H‐NMR. spectra.
