      abstract = {The allotropy of solid molecular nitrogen is the  consequence of a complex interplay between fundamental  intermolecular as well as intramolecular interactions.  Understanding the underlying physical mechanisms hinges on  knowledge of the crystal structures of these molecular  phases. That is especially true for ζ-N<sub>2</sub>, key to  shed light on nitrogen’s polymerization. Here, we perform  single-crystal X-ray diffraction on laser-heated  N<sub>2</sub> samples at 54, 63, 70 and 86 GPa and solve  and refine the hitherto unknown structure of  ζ-N<sub>2</sub>. In its monoclinic unit cell (space group  C2/c), 16 N<sub>2</sub> molecules are arranged in a  configuration similar to that of ε-N<sub>2</sub>. The  structure model provides an explanation for the previously  identified Raman and infrared lattice and vibrational modes  of ζ-N<sub>2</sub>. Density functional theory calculations  give an insight into the gradual delocalization of  electronic density from intramolecular bonds to  intermolecular space and suggest a possible pathway towards  nitrogen’s polymerization.},
