N2 - Donor-acceptor compounds of higher selenium and sulphur oxides with organic oxygen donor attract relatively low attention, even thought a high Lewis acidity of these oxides and basicity of oxygen atoms in organic oxygen donor molecules imply their existence and in the case of sufficient stability also their practical use. In our attempts to isolate a stable adduct of selenium trioxide we used pyridine-N-oxide as an oxygen base with no groups capable of migration. A white microcrystalline DA-complex C5H5NO.SeO3 was isolated by the reaction both components in nitromethane in nearly quantitative yield. The adduct was characterized by RA spectroscopy, elemental and X-ray structure analyses. C5H5NO.SeO3 is thermally stable and it is possible to store it for several months at laboratory temperature. If the reaction mixture is left without any disturbance for two weeks, crystals of 2pyO.Se2O5 appeared, as a result of redox reaction leading to this Se(IV)/Se(VI) compound.
