(2E,6E)-2,6-bis(2-chlorobenzylidene) cyclohexanone was synthesized and characterized by proton and carbon nuclear magnetic resonance, infrared, ultraviolet-visible, mass spectral analysis and X-ray crystallography techniques. Quantum Chemical calculations were done using Becke3-Lee-Yang-Parr with 6-31, 6-311, 6-311 + and 6-311++G (d, p) as basis sets and CAM-B3LYP with 6-31G(d,p) as the basis set. A good correlation between calculated and experimental spectroscopic data has been accomplished. Ultraviolet-Visible spectrum of the molecule was recorded in the region 200–500 nm and the electronic properties and composition were obtained using Time Dependent Density Functional Theory method. X-ray parameters (bonds, bond angles and torsion angles), Electric dipole moment, Mulliken atomic charges, polarizability and first static hyperpolarizability values have been calculated. Hyperconjugative interactions were studied with the help of natural bond orbital analysis. The thermodynamic properties of the compound were calculated at different temperatures.
