Tetraselenium tetranitride is the inorganic compound with the formula Se4N4. Like the analogous tetrasulfur tetranitride S4N4, Se4N4 is an orange solid. It is however less soluble and more shock-sensitive than S4N4.
As determined by X-ray crystallography, Se4N4 adopts a cage structure similar to that of S4N4. 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 of Se2N2.
