Tetraselenium tetranitride is the inorganic compound with the formula . Like the analogous tetrasulfur tetranitride ,  is an orange solid. It is however less soluble and more shock-sensitive than .
As determined by X-ray crystallography,  adopts a cage structure similar to that of . 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,  reacts with aluminium chloride to form adducts of .
