Chemical compound
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]
