  Conformational and structural analysis of bis(4-chloroquinoline-N-oxide)hydrogen tribromide

  摘要：

  The X-ray diffraction and conformational study of bis(4-chloroquinoline-N-oxide)hydrogen tribromide is performed. Two conformations corresponding to the minima on the energy curve are found by DFT using the ABINIT software. The model of one of the conformers generally matches with the structure determined experimentally for this compound using X-ray diffraction. In both instances, the structure with the dihedral angle (quinoline - N-O-H) close to 90A degrees is most favorable, which is explained in terms of resonance theory and steric factors. It is concluded that oxygen atoms in the complex are in the sp (3) hybridization state and the sp (2) hybrid state of the oxygen atom is not possible here due to steric factors.
