四氮化四硒是一种无机化合物，化学式为Se₄N₄，受热或受力易爆。^[1]

制备

四溴化硒在苯中和氨反应，可以得到四氮化四硒。^[5]二氧化硒和Me₃SiN=PMe₃（Me为甲基）在4 °C时于乙腈中反应，可以结晶出β-Se₄N₄。^[6]

性质

四氮化四硒不稳定，遇到震动极易爆炸：^[7]

Se₄N₄ → 4 Se + 2 N₂↑

四氮化四硒和干燥的溴化氢反应，得到Se₄N₃Br。^[5]它和五氯化钼在沸腾的二氯甲烷中反应，可以得到[Cl₄Mo=N=SeCl]₂；^[8]和六氯化钨在沸腾的二氯甲烷中反应，得到[WCl₄(NSeCl)]₂。^[9]

它和一些金属盐反应，也能产生含Se₂N₂单元的化合物，如(AlBr₃)₂(Se₂N₂)^[10]、[Bu₄N]₂[Pd₂Br₆(Se₂N₂)]^[11]等。
