New palladium complexes with 7-azaindole (7AI) have been synthesized.
The trans structure was confirmed by single crystal XRD, FT-IR, FT-Raman studies.
A detailed interpretation of the IR and Raman spectra is reported.
Controversial assignment of the Pd–N stretching vibrations is elucidated.
NBO analysis reveals strong electron delocalization in the complex.
