Аннотация

Using MPW1PW91 quantum chemical calculations, we report structures, frontier orbital analysis, natural bond analysis, and aromaticity of the C5H5Ir(PH3)3 iridabenzene and XC5H4Ir(PH3)3para-substituted iridabenzenes. The substituent effects were estimated from the donor-acceptor interaction energies of the natural bond orbitals of substituent and iridabenzene frame. Nucleus-independent chemical shift (NICS) has been evaluated to understand the aromaticity. Time dependent density functional theory (TD-DFT) is used to calculate the energy, oscillatory strength and wavelength absorption maxima (lmax) of electronic transitions and their nature. Changes in hyperpolarizability of molecules are studied. Influence of solvent on the structure, frontier orbital energies, λmax, and hyperpolarizability of C5H5Ir(PH3)3 iridabenzene has been studied.
