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
[编辑]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
[编辑]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。
