Molecular Orbitals Study in Pt(PPh3)2-(η2C60)
Abstract:
The molecular orbitals of the complex Pt(PPh_3)_2-η~2(C_(60)) were investigated via Fenske-Hall molecular orbital calculations on the prototype species Pt(PH_3)_2-η~2C_(60). The results was compared with typical π-complex Pt(PPh_3)_2-η~2C_2H_4. The results of calculation showed that the components of HOMO and LUMO in Pt(PH_3)_2-η~2C_(60) mainly come from C_(60), which is the electron acceptor, but the components of HOMO and LUMO in Pt(PH_3)_2-η~2C_2H_4 molecular orbitals mainly come from Pt(PH_3)_2, which is the electron donor. The ligand C_(60) and C_2H_4 both act as an acceptor, but C_(60) is more stronger than C_2H_4. The LUMO of Pt(PH_3)_2-η~2C_(60) is still situated at lower energy and it is possible to accept further Pt(PH_3)_2 radical on C_(60) surface. From the calculation it was revealed that there are two conjujated chain started on atoms C1 and C6. The Mulliken charge is distributed along these chain alternatively.
