the molecular structure optimized by DFT were consistent with the crystal structures determined by single crystal X-ray diffraction. The molecular electrostatic potential and frontier molecular orbitals of the title compound were further investigated by DFT, and some physicochemical properties of the compound are revealed. In additional, the intermolecular interactions in the crystal were investigated
