Abstract: The molecular orbital energy, charge distribution, and Mulliken's bond order in neodymium chloride complex with isopropanol have been calculated with an INDO method. The calculation showed that after coordination, the molecular orbi tal energies corresponding to Nd—Cl bond were increased, the Nd—Cl bond orders were decreased, and the net charges on Nd and Cl were decreased. The results indi cate that the charge transfer of Cl→Nd caused by orbital overlapping and the re pulsion of negative charge added on Nd against the valent charge of Nd—Cl lead to increasing the energy levels and weakening the Nd—Cl bonds, which effectively activates the Nd—Cl bonds. It can be expected that the alkylation reaction to form active species may be favorably carried out.
Besides, the complex activation for Nd—Cl is of certain choice.
