addition, IR frequencies, 1 H and 13 C NMR chemical shifts of compound 8 were also calculated by using DFT calculations at the same level basis set. The calculated geometrical parameters, IR frequencies, 1 H and 13 C NMR chemical shifts of the compound 8 were in good agreement with the observed single crystal-XRD data, IR, 1 H and 13 C NMR spectral values.
