X-ray structure and DFT study of neutral mixed phosphine azoimine complexes of ruthenium
Geometry optimization for a cis-[RuII(dppe)LCl2] (1-8) {L = C6H5NNC(COCH3)NAr, Ar = 2,4,6-trimethylphenyl (L1), 2,5-dimethylphenyl (L2), 4-tolyl (L3), phenyl (L4), 4-methoxyphenyl (L 5), 4-chlorophenyl (L6), 4-nitrophenyl (L7), 2,5-dichlorophenyl (L8); dppe = Ph2P(CH2) 2PPh2} was effected using the gaussian 03 protocol at density functional theory (DFT) B3LYP level with 6-31G/lanl2dz mixed basis. In addition, the complex cis-[RuII(dppe)L3Cl2] (3) has been further characterized by X-ray diffraction analysis. It was found that the optimized structure using 6-31G/lanl2dz has a large agreement with the X-ray data. DFT calculations show that upon solvation both Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) molecular orbitals are stabilized and their energy gap is increased. TD-DFT calculations show that the intense broad band centered at lambdamax ? 506 nm is assigned to “mixed metal-ligand-to-ligand charge-transfer” (MMLLCT) while the weak low energy band centered on ?840 nm is assigned to the pure MLCT transition. The low intensity for the low energy MLCT transition can be explained by the large mixing between the azoimine (L) and (Ru(dpi)) orbital.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 10049-08-8, you can also check out more blogs about10049-08-8
