The pentazolate anion shows great promise for high energy density materials, but has only been isolated alongside non-energetic counter ions that impede its energetic properties. Here, the authors synthesize a silver cyclo-N5-complex devoid of stabilizing ions, as well as a complementary [Ag(NH3)2]+[Ag3(N5)4]− 3D framework.
