to investigation non-bonded interaction of the [cuf4]2- complex inside nanoring, we focus on the single wall boron-nitride b18n18 nanoring. thus, the geometry of b18n18 nanoring has been optimized by b3lyp method with epr-ii basis set and geometry of the [cuf4]2- complex has been optimized at b3lyp method with def2-tzvp basis set and stuttgart rsc 1997 effective core potential. also electronic ...

Singly occupied molecular orbital?highest orbital (SOMO?HOMO) conversion (inversion), SHC, is a phenomenon in which the SOMO lower energy than doubly orbitals (DOMO, HOMO). A non-Aufbau electronic structure leads to unique properties such as switch bond dissociation and generation of high-spin species on one-electron oxidation. In addition, pronounced photostability these has been reported rece...

In this research DFT/B3LYP method has been employed to investigate the geometrical structures,relative stabilities, and electronic properties of Cun (n=3–10) clusters for clarifying the effect of sizeon the properties. Through a careful analysis of the successive binding energies, second-orderdifference of energy and the highest occupied-lowest unoccupied molecular orbital energy gaps as afunct...

The regioselectivity of 1,3-dipolar cycloaddition reactions between mesoionic compounds with singly-tethered substituents is examined. The results with propitiate dipolarophiles are compared with other singly and doubly-tethered examples according to a model using an asynchronous, concerted transition state. The isolation and reaction of a novel, nonaryl substituted mesoionic compound 7 is repo...

A novel Pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [Co(NO3)2].6H2O has been obtained by the reaction of Pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. The structures of [Co(pydc)(Phen)(H2O)](pydcH2).4H2O receptors, and their complexes were optimized using DFT method at the B3LYP/3-21G** level. The highest occupied molecular o...

First-principle calculations were carried out to investigate the adsorption of CO over Cun nanoclusters. The structural, spectroscopic and electronic properties like optimized geometries, HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energy levels, binding energy, adsorption energy, vibrational frequency and density of states (DOSs) of the p...
