Discovery of Elusive ‘Black’ Nitrogen Structure Finally Solves Chemistry Mystery

When it comes to putting the lighter elements of the periodic table under high pressure, nitrogen seems to be the odd one out. While oxygen, boron, and carbon all change structure according to a specific pattern, nitrogen does not, a glaring anomaly scientists have struggled to resolve.

Reading technical paper. Unfortunately, the identification of the “black nitrogen (bp)” phase relies on assuming a 4% error in a previous calculation from 2014. Without the error, what’s observed would be the better known cg phase.
