Abstract :
Argentophilic interaction has been studied in silver methylhydantoin complex {[Ag(1-methylhydantoin)]·0.5H2O}n using electronic, Raman and X-ray absorption spectroscopies strengthened theoretically. The EXAFS confirmed coordination number (CN = 3) of complex and metalophilic interactions. The digital filter analysis of electronic spectra revealed that broad bands at ca 38 000 cm−1 and ca 45 000 cm−1 observed in the solid state and solutions, respectively, were composed of two transitions, namely L–L(π → π∗) and Ag–Ag tentatively assigned to (4dσ∗ → 5pσ) in silver ion. The Raman spectroscopy data showed a new band at 83 cm−1 assigned to ν(Ag2) vibration theoretically supported by DFT.
