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.[2]

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°.[1][3]

Among its many reactions,[4][5] Se4N4 reacts with aluminium chloride to form adducts of Se2N2.[6]
