Abstract
The structures and properties of quintet pyridyl-2,6-dinitrenes formed by low-temperature photolysis of 2,6-diazidopyridines were studied by ESR and quantum chemical (B3LYP/6-31G*) methods. The synthesized dinitrenes represent a new type of quintet tetraradicals for which the ratio of zero-field splitting parameters is ¦ E q¦/¦D q¦ = 1/3. This ratio is characteristic of quintet molecules in which the vector angle between two biradical centers is close to 114.5°.
