摘要

The p-tolylimido rhenium(V) complexes [Re(p-NC_6H _4CH_3)X_3(EPh_3)_2] (X = Cl, Br; E = As, P) and [Re(p-NC_6H_4CH_3)Cl _2(hmpbta)(PPh_3)]·MeCN have been synthesized and characterized spectroscopically and structurally. The electronic spectra of [Re(p-NC_6H_4CH_3)Cl_3(PPh _3)_2] and [Re(p-NC_6H_4CH _3)Cl_2(hmpbta)(PPh_3)] were investigated at the TDDFT level employing B3LYP functional in combination with LANL2DZ. Additional information about bonding between the rhenium atom and p-tolylimido ligand in the complexes [Re(p-NC_6H_4CH_3)Cl _3(PPh_3)_2] and [Re(p-NC_6H _4CH_3)Cl_2(hmpbta)(PPh_3)] was obtained by NBO analysis.

The electronic spectra of [Re(p-NC_6H_4CH_3)Cl _3(PPh_3)_2] and [Re(p-NC_6H _4CH_3)Cl_2(hmpbta)(PPh_3)](Hhmpbta-2- (2′-hydroxy-5′-methylphenyl)benzotriazole) were investigated at the TDDFT level employing B3LYP functional in combination with LANL2DZ. Additional information about bonding between the rhenium atom and p-tolylimido ligand in the complexes [Re(p-NC_6H_4CH_3)Cl _3(PPh_3)_2] and [Re(p-NC_6H _4CH_3)Cl_2(hmpbta)(PPh_3)] was obtained by NBO analysis.
