Bucknum, M. J. and E. A. Castro (2012). "On the n-diamond and i-carbon nanocrystalline forms." Journal of Mathematical Chemistry 50(5): 1034-1038.

We report on a comparison of the diffraction pattern observed for nanocrystalline n-diamond and i-carbon forms by other investigative teams, with the calculated diffraction pattern of glitter based upon lattice parameters optimized using the DFT-CASTEP method. The close fit of the latter dataset to that observed for n-diamond and i-carbon, as reported herein, suggests that indeed i-carbon may be of the same structure as n-diamond, and that they both may have the tetragonal glitter structure.
