Popis: | The title molecule, N,N' -(azanediyl bis (2,1-phenylene)) bis (2-chloropropanamide) (L NNN ) was synthesized and characterized by means of Hirshfeld surface analysis and vibrational (FT-IR and RAMAN) studies. Ab-initio Hartree-Fock (HF) and density functional theory (DFT; BLYP, B3LYP, B3PW91 and mPW1PW91) calculations were accomplished using 6-31G(d,p) and 6-311G(d,p) basis sets. The comparison of calculated bond lengths and angles with X-ray crystal structure shows sufficient agreement. The solid phase FT-IR and FT-RAMAN spectra of L NNN have been recorded in the regions 4000-525 cm -1 and 4000-50 cm -1 , respectively. A comparative analysis between the calculated and experimental vibrational frequencies was carried out and significant bands were assigned. The results indicated a good correlation between experimental and theoretical IR and RAMAN frequencies. A detailed analysis of the intermolecular interactions via Hirshfeld surface analysis and fingerprint plots revealed that supramolecular structure of the L NNN is stabilized mainly by the formation of H···H, C···H, Cl···H ve O···H intermolecular interactions. |
