Neon is the fifth most abundant element in Earth’s atmosphere and a vital part of the semiconductor industry, yet it was only very recently that the element was able to be observed in an organic crystal. Neon is a noble gas and doesn’t really want to share its electrons. This makes it incredibly difficult to capture a compound including neon. In late 2015, researchers used a highly porous material known as a Metal-Organic Framework (MOF) to capture neon crystals. They then used the technique known as Powder X-ray Diffraction to determine the location of the neon in the pore of the MOF. The first crystal structures of neon in this type of organic environment were published in 2016.
