Tetraselenium tetranitride
Tetraselenium tetranitride is the inorganic compound with the formulaSe4N4. Like the analogous tetrasulfur tetranitrideS4N4,Se4N4 is an orange solid. It is however less soluble and more shock-sensitive thanS4N4.
As determined by X-ray crystallography,Se4N4 adopts a cage structure similar to that ofS4N4. The Se−Se and Se−N distances are 2.740 and 1.800 Å, respectively. The N−Se−N angles are 90°.
Among its many reactions,Se4N4 reacts with aluminium chloride to form adducts ofSe2N2.
