spectra have been measured at 647.5 nm excited laser lines in the frequency range 125–4000 cm−1. The Raman spectrum is characterized by a series of bands in the 150–3500 cm−1 spectral range. The structure of the this compound was optimized by density functional theory (DFT) using B3LYP method and shows that the calculated values obtained by B3LYP/6-31G(d,p) basis are in much better agreement with the
