      abstract     = {Being a noble metal, silver is known for its chemical
                      inertness. Molecular nitrogen, due to its extremely strong
                      covalent triple bond, is also typically considered
                      unreactive. It is thus unsurprising that no credible report
                      on the formation of a thermodynamically stable silver and
                      nitrogen compound exists. In this study, we report the
                      synthesis of silver pentazolate (AgN5), achieved through the
                      direct reaction of elemental silver with molecular nitrogen
                      at a pressure of 118(3) GPa and a temperature of 2000(200)
                      K. The crystal structure of AgN5 was determined from
                      synchrotron single-crystal X-ray diffraction (SCXRD) data,
                      revealing it to be comprised of cyclo-N5– anions.
                      Remarkably, this solid’s structure does not correspond to
                      any of the silver nitrides previously predicted. Moreover,
                      density functional theory (DFT)-based enthalpy convex hull
                      calculations demonstrate that this AgN5 compound is the only
                      thermodynamically stable Ag–N solid between 10 and 120 GPa
                      while also providing information on its phonon and electron
                      band structures, including its electronic band gap. Both DFT
                      calculations and SCXRD experimental data yield insights into
                      the stability pressure range of AgN5 upon decompression.
                      This study provides yet another example of the capability of
                      high pressure and high temperature to facilitate
                      unprecedented chemical reactions between elements often
                      assumed to be inert, in turn enabling the formation of novel
                      nitrogen-rich compounds.},
