Abstract

Charged molecular species, such as ${{[{\mathrm{N}}_{2}]}^{x}}^{\text{--}}$, ${{[{\mathrm{O}}_{2}]}^{x}}^{\text{--}}$, ${{[{\mathrm{C}}_{2}]}^{x}}^{\text{--}}$, and ${{[{\mathrm{S}}_{2}]}^{x}}^{\text{--}}$, follow the paradigm of carrying integer values of electrons. Here, the ${\mathrm{Na}}_{3}{({\mathrm{N}}_{2})}_{4}$, ${\mathrm{Ca}}_{3}{({\mathrm{N}}_{2})}_{4}$, ${\mathrm{Sr}}_{3}{({\mathrm{N}}_{2})}_{4}$, and $\mathrm{Ba}{({\mathrm{N}}_{2})}_{3}$ compounds were produced and characterized 70 GPa and evidenced to be composed of paradigm-breaking ${{[{\mathrm{N}}_{2}]}^{x}}^{\text{--}}$ dimers with noninteger charges of \ensuremath{-}0.75, \ensuremath{-}1.5, \ensuremath{-}1.5, and \ensuremath{-}0.67, respectively. The anion-driven metallicity of the compounds is proposed as the physical mechanism enabling the noninteger electron count of the ${{[{\mathrm{N}}_{2}]}^{x}}^{\text{--}}$ dimers. The properties of these dimers and the compounds bearing them are demonstrated to depend on their noninteger charge, paving the way to materials with electron-tunable features.
