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.
