中文摘要 | Two types of transition metal-benzene anion complexes, (titanium)(n)(benzene)(m)(-) and (cobalt)(n)(benzene)(m)(-) (n <= 2, m <= 3) have been determined using density functional theory. The photoelectron spectra of Ti(n)Bz(m)(-) and Co(n)Bz(m)(-) (n <= 2, m <= 3) were discussed from the perspective of quantum chemical calculations of the vertical detachment energies (VDEs) of several low-energy isomers obtained by the structural optimization procedure. The binding of Ti and Co atoms to benzene molecules is accounted by 3d-pi bonds, as revealed by the molecular orbitals. The topology of the electronic density has been analyzed, suggesting that the C-C bonds were weakened in the transition metal-benzene complexes in comparison to those in free benzene. Spin density distribution results show the spin densities for Ti(n)Bz(m)(-) and Co(n)Bz(m)(-) (n <= 2, m <= 3) reside mainly on the metal Ti and Co centers (70%-90%). A shift to lower magnetic moment with respect to the pure titanium/cobalt cluster anions indicates the solvent benzene molecule acts to demagnetize the bare titanium/cobalt cluster anions. |
