Pentazenium tetraazidoborate is an extremely unstable chemical compound with the formula N5[B(N3)4]. It is a white solid that violently explodes at room temperature. This compound has a 95.7% nitrogen content which is the second highest known of a chemical compound, exceeding even that of ammonium azide (93.3%) and 1-diazidocarbamoyl-5-azidotetrazole (89.1%),[1] being surpassed only by hydrazoic acid (97.7%).
