- High-pressure nitrogen chemistry has expanded at a formidable rate over the past decade, unveiling the chemical richness of nitrogen. Here, the Zn-N system is investigated in laser-heated diamond anvil cells by synchrotron powder and single-crystal X-ray diffraction, revealing three hitherto unobserved nitrogen compounds: beta-Zn3N2, alpha-ZnN4, and beta-ZnN4, formed at 35.0, 63.5, and 81.7 GPa, respectively. Whereas beta-Zn3N2 contains the N3- nitride, both ZnN4 solids are found to be composed of polyacetylene-like [N-4](infinity)(2-) chains. Upon the decompression of beta-ZnN4 below 72.7 GPa, a first-order displacive phase transition is observed from beta-ZnN4 to alpha-ZnN4. The alpha-ZnN4 phase is detected down to 11.0 GPa, at lower pressures decomposing into the known alpha-Zn3N2 (space group Ia (3) over bar) and N-2. The equations of states of beta-ZnN4 and alpha-ZnN4 are also determined, and their bulk moduli are found to be K-0 = 126(9) GPa and K-0 = 76(12) GPa, respectively.
