| Outline of Final Research Achievements |
We have succeeded the synthesis, isolation, and structure ditermination of chalcogenonium (telluronium and selenonium) salts bearing three ppy ligans. These structure have a hexa-coordinated and a distorted octahedral structure with only facial configuration. These properties of compounds were estimated by DFT calculation. We found that the orbital of lone electron pair locate on central chelcogen atoms. These results indecate that these compounds are new species which have [14-Ch-6]+(Ch = Se, Te). Furthermore, in order to estimate the bond properties between chalcogen atoms and nitrogens, these compounds were calculated by AIM (Atoms in Molecule) alalysis. The Ch-N moieties were characterized by the week bonds.
